Postal voting in the United States


Postal voting in the United States, domestically referred to as vote-by-mail, mail-in voting, or Vote from Home, is a form of absentee ballot in the United States, in which a ballot is mailed to the home of a registered voter, the voter fills it out and returns it via postal mail or drops off the ballot in-person into a secure drop box or at a voting center. This process reduces the requirements to staff and run polling centers during an election. All-mail elections can save money,
while a mix of voting options can cost more.
Balloting materials may be sent via the United States Postal Service without prepayment of postage. Vote-by-mail has been implemented in both Republican and Democratic states.
Research shows that the availability of postal voting increases turnout. Postal voting has a greater risk of fraud than in-person voting though there are relatively few known instances of such fraud. Per one database, there were 491 cases of absentee ballot fraud from 2000 to 2012; a period in which billions of votes were cast.
Election offices rejected 67,000 ballots in the 2018 election and 92,000 in the 2016 election, because mis-matched signatures led officials to believe someone could have forged those ballots. If they were not forged, voters were disenfranchised.
Processing large numbers of ballots and signature verifications accurately has numerous challenges other than fraud.

Process

Absentee ballots started for the military during the Civil War. For many years after, these ballots were for people who could not go to the polling place on election day. Now some states let them be used for convenience, but state laws still call them absentee ballots.
Some states let voters with permanent disabilities apply for permanent absentee voter status, and some other states let all citizens apply for permanent status, so they will automatically receive an absentee ballot for each election. Otherwise a voter must request an absentee ballot before the election occurs.
Ballots or applications for postal ballots are sent out before the election date, by a margin which depends on state law. In some states, a voter's pamphlet is also distributed. The election office prints a unique barcode on the return envelope provided for each ballot, so processing of each envelope can be tracked, sometimes publicly,
and corresponding signature files can be loaded quickly to check the voter's signature on the envelope when it returns.
Voters who lose the return envelope can still vote by obtaining another envelope from election officials, or in some jurisdictions by using a plain envelope.
To vote by mail, an individual marks the ballot for their choice of the candidates, places it in the provided mailing envelope, seals it and signs and dates the back of the mailing envelope. Some jurisdictions use one envelope or privacy sleeve inside an outer envelope, for privacy. The envelope containing the ballot is then either mailed, or dropped off at a local ballot collection center.
The deadline is determined by state law. In some jurisdictions, postmarks do not count, and ballots must be received by a certain time on election day. In other jurisdictions, a ballot must have a postmark on or before the day of the election and be received prior to the date of certification. Many vote-by-mail jurisdictions enlist the help of volunteers to take ballots in walk-up Drop off Booths or drive-up Quick Drop locations. The Help America Vote Act requires some polling options, often at central election headquarters, with voting machines designed for disabled people.
It is sometimes inaccurately claimed that absentee ballots are not counted unless the race is close; in fact, all valid absentee ballots are counted even if they will not affect the outcome of the election.
In the 2016 US Presidential election, approximately 33 million ballots were cast via mailed out ballots. That resulted from a combination of the jurisdictions that used only vote-by-mail plus absentee votes in other jurisdictions.
In April 2020, during lockdowns for the coronavirus pandemic, an NBC News/Wall Street Journal poll found that 58 percent of American voters would favor nationwide election reform to allow everyone to vote by mail.

Voting from abroad (UOCAVA)

In 2018, 350,000 ballots came through procedures of the Uniformed and Overseas Citizens Absentee Voting Act, from military and merchant marine voters stationed inside or outside the United States, and other citizens living outside the United States. In 1986 Congress enacted UOCAVA, which requires that the states and territories allow United States citizens residing outside the United States, as well as members of the United States Uniformed Services and merchant marine, and their family members, inside or outside the United States, to register at their last residence in the US, and vote absentee in elections for Federal offices. Most states and territories also let these citizens vote in state and local elections, and most states let citizens who have never lived in the US vote at their parents' last address.
Though many states had pre-existing statutes in place, UOCAVA made it mandatory and nationally uniform. Voters eligible for UOCAVA who do not receive an absentee ballot from their state in time to vote, may use the Federal Write-In Absentee Ballot. The voter's signature goes on an information sheet enclosed with this ballot, not on the envelope. It requires following state requirements for witnesses, but not for notaries. Almost half the states require ballots to be returned by mail. Other states allow mail along with some combination of fax, or email; four states allow a web portal. West Virginia experimented with smart phone approaches, but no longer offers them.
Since 1997 Texas has let astronauts vote from space.

In states

The National Conference of State Legislatures has many tables showing rules about postal voting in every state.
In 1998, voters in Oregon passed an initiative requiring that all elections be conducted by mail. Voters may also drop their ballots off at a county designated official drop site. Oregon has since reduced the cost of elections, and the time available to tally votes has increased. Oregon requires receipt of votes by 8:00pm local time on election day. County elections offices collect from post offices at their closing time on election day and from drop boxes at 8:00pm election day. Any valid ballot received by 8:00pm local time on election day by any county is required to be counted, unless the cumulative votes of any valid ballots transferred to the relevant county elections office after the closing of the polls cannot change the outcome of the election for any given seat. Voter turnout is among the highest in Oregon.
In 2011, the Washington legislature passed a law requiring all counties to conduct vote-by-mail elections. Local governments in Washington had the option to do so since 1987, and statewide elections had permitted it since 1993. By 2009, 38 of the state's 39 counties had conducted all elections by mail. Pierce County joined the rest of the state in all-mail balloting by 2014. In Washington, ballots must be postmarked by election day, which helps to ensure all voters' votes are counted; ballot counting takes several days after election day to receive and process ballots. Beginning in 2018 postage is prepaid so voters do not have to use a stamp.
In 2013, Colorado began holding all elections by mail. A Pantheon Analytics study of the 2014 election showed a significant uptick in voter participation from what would have normally been "low propensity" voters. A PEW Charitable Trust study of the same election showed significant cost savings.
In 2014, Utah started allowing each county to make their own decision regarding whether to go to all mailed-out ballots. In the 2016 general election, 21 of 29 counties did so. That rose to 27 of 29 counties in 2018, covering over 98% of their electorate, with all counties doing so in 2020. A Pantheon Analytics study of Utah's 2016 general election showed a 5-7% point higher turnout in the counties using vote by mail than those with traditional polling places, with even higher differences among younger voters.
In 2016, California passed SB 450 which authorizes a roll-out of vote by mail across the state, at county discretion. For the 2018 elections, 14 counties were authorized to vote by mail and five ultimately did so: Madera, Napa, Nevada, Sacramento, and San Mateo. In each of those five counties, voter turnout was higher than the average turnout for the state. For 2020, all counties will be authorized to do so, and as of 8 April 2020 the following ten additional counties have opted in: Amador, Butte, Calaveras, El Dorado, Fresno, Los Angeles, Mariposa, Orange, Santa Clara, and Tuolumne.
As of 2020, Colorado, Hawaii, Oregon, Utah, and Washington State conduct their elections entirely by mail; in many other states there are counties or certain small elections where everyone votes by mail.
California will mail every voter a ballot before the November 2020 election; California voters will also keep the option to vote in-person. Florida is considering postal voting for the November 2020 election.
In 2020 four states joined the majority of states which already allowed "no excuse" voting by mail : Michigan, Pennsylvania, Rhode Island, and Virginia. Other states have relaxed restrictions on mail in ballots for a total of 46 states to allow voting by mail due to Coronavirus-19.
Kansas conducted its Democratic primary in May 2020 entirely by mail. Hawaii used full vote by mail for all elections beginning with its primary in May 2020.
New Jersey will also conduct a primarily vote by mail election for the upcoming primary in July 2020 albeit a limited number of polling stations will be open for those who would vote provisionally as well as voters with disabilities. The Trump campaign sued Pennsylvania to require voters to mail their ballot in a secrecy envelope or else to personally deliver it to an official county election office.
Other jurisdictions are now starting to experiment with vote by mail, or run pilot programs. 31 of 53 counties in North Dakota now vote by mail, as do over 1000 precincts in Minnesota. In 2018, pilot programs in Anchorage, Alaska exceeded previous turnout records and Garden County, Nebraska saw higher turnout versus the state average. Rockville, Maryland piloted vote-by-mail in 2019. In 2018, Connecticut's Governor issued Executive Order 64, directing a study of a possible move to vote by mail.

Turnout

Insofar as postal voting makes the act of voting easier, it may facilitate a campaign's "get out the vote" efforts. Campaigns can also target potential voters more efficiently by skipping those whose ballots have already been processed by the elections office. On the other hand, face-to-face canvassing has been found to be less effective with postal voting.
In 2016, the US Government Accountability Office issued a report outlining turnout improvements seen in vote by mail elections.
Researchers in 2020 confirm that studies have shown increased turnout "mainly for those who already vote." In Colorado they found overall turnout rose 9 percentage points, while it rose 16 percentage points among young people, 13 among African-Americans, 11 among Asian-Americans, 10 among Latinos, blue-collar workers, those without a high school diploma, and those with less than $10,000 of wealth.

Reliability of postal ballots

Expansion in 2020

The Election Advisory Commission and National Conference of State Legislatures have published information on the staffing, equipment, space and procedures needed to handle large increases in postal ballots.
The National Vote at Home Institute, which advocates postal ballots, analyzed all states in 2020 and found that 32 states "are missing major pieces of policy or best practices that ensure a secure mail ballot process such as a sufficient data integrity process, signature verification processes and/or a signature deficiency cure process."
Among these 32 states, 15 lack steps to verify voters' addresses before mailing them ballots, 17 states do not mandate a signature verification process, and 30 do not have adequate options to cure defects in voter signatures. Often voters have no way to cure signature mis-matches.

Past problems

Postal ballots have been the source of "most significant vote-counting disputes in recent decades" according to Edward Foley, director of the Election Law program at Ohio State University.
Among the thousands of elections from 2000-2012, there were 491 known cases of absentee ballot fraud,
and the Heritage Foundation lists additional cases since 2012.
From 2003-2018, at least 15 local election results were thrown out in tight elections based in part on absentee voting fraud.
Richard Hasen, a professor at UC Irvine School of Law said "problems are extremely rare in the five states that rely primarily on vote-by-mail."
Justin Levitt, a law professor at Loyola Marymount University does not have statistics on postal ballot fraud, but said "I do collect anecdotal reports... misconduct in the mail voting process is meaningfully more prevalent than misconduct in the process of voting in person... Misconduct still amounts to only a tiny fraction of the ballots cast by mail."
Lonna Atkeson, an expert in election administration, said about mail-in voting fraud, "It’s really hard to find... The fact is, we really don’t know how much fraud there is... There aren’t millions of fraudulent votes, but there are some."
In 2018, a report from the US Senate Intelligence Committee of Russian meddling in the 2016 election pointed out that auditable paper ballots, by definition part of all vote by mail elections, were potentially safer than paperless voting systems,
which are still used in a few states. However only about half the states actually use paper ballots to conduct election audits.
Specific types of problems include:
These problems with postal ballots can be categorized as procedural issues, which may not have solutions; collection of ballots by dishonest collectors, which is partly controlled in many states by limits on the number of ballots which one person can deliver, though collectors can still mail in the ballots they collect,
and the 9th Circuit Court of Appeals disallowed Arizona's limits based on discriminatory intent;
signature verification, which has inherent errors and may have bias, and insider issues, which are partly addressed by enough staffing, quality control, and openness to observation by the public or candidates.
Some problems have inherently limited scope, such as family pressure and bribes, while others can affect several percent of the vote, such as signature verification.

Republican concerns in 2020

In 2020, President Donald Trump began to say that postal voting was highly vulnerable to fraud, stating postal ballots will be "substantially fraudulent. Mail boxes will be robbed, ballots will be forged & even illegally printed out & fraudulently signed". Republican politicians are divided on that issue, with some making similar claims about fraud, while others – including a considerable portion of Republican senators – have disavowed the president's concerns. Experts disagree with the expectation of substantial fraud.
On July 30, 2020 President Trump seemingly suggested postponing the 2020 presidential election based on his unsubstantiated claims about extensive postal voting fraud. of the Constitution grants Congress the power to determine the date of election day; currently established the 3rd November as presidential election day.

Security printing

Some states say they print postal ballots on special paper to prevent forgeries. Special papers, microprinting, magnetic ink and other measures are common to protect currency, bank checks and stamps. Election officials do not say they review ballots based on these methods, though the Labor Department reviews paper when considering if union election ballots are forged. States print bar codes on return envelopes to identify the voter, so a forger would need to know the coding system in order to forge bar codes.

Signature verification process

States do check signatures to prevent forged paper ballots. Signature mismatches were the most common reason for rejecting postal ballots in 2016 and the second most common, after late arrival, in 2018. While many states accept in-person votes without needing identification, most require some verification on postal ballots. Six states and DC simply require a signature on the ballot envelope, without verifying the signature, 44 states require the signature to match one on file, and some of these states require witnesses or notaries.
The first step after receiving mailed ballots is to compare the voter's signature on the outside of the envelope with one or more signatures on file in the election office. Smaller jurisdictions have temporary staff compare signatures. Larger jurisdictions use computers which scan envelopes, quickly decide if the signature matches well enough, and set aside non-matches in a separate bin. Temporary staff then double-check the rejections, and in some places check the accepted envelopes too.
Error rates of computerized signature reviews are not published. The best academic researchers have 10-14% error rates. Algorithms:
look for a certain number of points of similarity between the compared signatures… a wide range of algorithms and standards, each particular to that machine's manufacturer, are used to verify signatures. In addition, counties have discretion in managing the settings and implementing manufacturers' guidelines… there are no statewide standards for automatic signature verification… most counties do not have a publicly available, written explanation of the signature verification criteria and processes they use.

Handwriting experts say "it is extremely difficult for anyone to be able to figure out if a signature or other very limited writing sample has been forged," In manual signature reviews, "election officials with little or no training in verifying a person's signature are tasked with doing just that… it's unlikely that only one or two samples will show the spectrum of a person's normal variations…"
Colorado's guide for manual verification is recommended by the federal government. Colorado accepts any signature which matches on: cursive v. printed, flowing v. slow and deliberate, overall spacing, size, proportions, slanted v. straight, spelling and punctuation. When signatures do not match on these items, staff still accept them if staff can think of a reasonable explanation for differences.
In a California study, most counties, when they manually reviewed ballot signatures, had "a basic presumption in favor of counting each ballot… declare that just three or even one matching characteristic between the ballot signature and the comparison signature will be sufficient to find a match… "
Texas officials must use their "best judgment" without training.
In 16 states, when election offices reject signatures, they notify the voters so they can mail another signature, which may be just as hard to check, or they can come to the office and vouch for the envelope, usually in less than a week; the other 36 states have no process to cure discrepancies.
Notification by US mail results in more cures than email or telephone notice.
Rejected envelopes, with ballots still unseen in them, are stored in case of future challenges. Accepted envelopes are opened and separated from the envelopes in a way that no one sees the external name and the ballot choices. The Election Advisory Commission says machines can help, but this step requires the most space of any step, especially when workers have to be 6 feet apart.

Unequal signature rejection rates

The highest error rates in signature verification are found with lay people, higher than for computers, which in turn make more errors than experts.
Researchers have published error rates for computerized signature verification. They compare different systems on a common database of true and false signatures. The best system falsely rejects 10% of true signatures, while it accepts 10% of forgeries. Another system has error rates on both of 14%, and the third-best has error rates of 17%.
It is possible to be less stringent and reject fewer true signatures, at the cost of also rejecting fewer forgeries, which means erroneously accepting more forgeries.
Vendors of automated signature verification claim accuracy, and do not publish their error rates.
Voters with short names are at a disadvantage, since even experts make more mistakes on signatures with fewer "turning points and intersections."
The National Vote at Home Institute reports that 17 states do not mandate a signature verification process.
In the November 2016 general election, rejections ranged from none in Alabama and Puerto Rico, to 6% of ballots returned in Arkansas, Georgia, Kentucky and New York.
In 2020 special elections in New Jersey, 10% of postal ballots were rejected, much higher than the 3% rejections in the 2018 general election in New Jersey. The rise was largely attributed to inexperience of many voters using postal ballots for the first time, though some elections have resulted in charges regarding voter fraud. One such race was the Paterson municipal election, where 19% of ballots cast were disqualified. Approximately 800 of the more than 3190 votes disqualified were related to the various voter fraud allegations.
Where reasons for rejection were known, in 2018, 114,000 ballots arrived late, 67,000 failed signature verification, 55,000 lacked voter signatures, and 11,000 lacked witness signatures in states which require them.
Rejection rates are higher for ballots which claim to come from young or minority voters. In the 2020 primary and 2016 general elections, Florida officials rejected 4% of postal ballots which claimed to come from voters aged 18-25. In the 2018 general election they rejected 5%. In Florida over age 60 or 65, rejections were only a percent in 2020, two thirds of a percent in 2018 and half a percent in 2016. However over age 90, rejection rates were above average, though not as high as under age 25. Rejections were 2% for ballots claiming to come from Florida non-white voters, and 1% from white voters in all three years.
In the 2018 Florida election, 4% of postal ballots from military voters stationed inside the United States were rejected.
Florida voters are not allowed to cure signature problems if these are discovered after election day.
Florida rejection rates in 2016 varied by county, ranging from none to 4%, and up to 5% for ballots which claimed to come from blacks or hispanics in some counties. Two counties with large universities rejected 9% of 18-21-year-olds: Alachua and Orange, while Pinellas, which also has large universities, rejected 0.2% of this age range.
In Georgia's 2018 general election, most counties rejected higher fractions of ballots claiming to come from black or Hispanic voters than from white voters. The higherst rejection rates for ballots which claimed to come from black voters were in Polk 17%, Taylor and Clay 16%, Putnam, and Warren 14%, Atkinson and Candler 13%, McIntosh 12%, and Glynn 10%. For Hispanics, Thomas and Putnam counties rejected 20%, Bulloch 14%, Barlow 12%, Glynn 11%, Decatur 10%. The highest rates for whites were Pickens 13%, Coffee and Polk 10%. Researchers also found higher rejection rates for women, which they hypothesized could relate to name changes not updated at the voter registration office,
though issues with hyphenated last names can also cause signature rejections.
Bias in computer verification depends on the set of signatures used for training the computer, and bias in manual review depends on whether the temporary staff recognize names as non-white.
Many voter registrations, especially for younger voters, come from driver's license applications, where the signature was done on an electronic signature pad. People move their hands differently when signing on paper and on electronic pads. Further the pads used have low resolution, so distinctive elements of paper signatures on the ballot envelopes, are blurred or omitted in the electronic signatures used for comparison. Signatures also have more variation, and therefore are harder to verify, when they come from people who rarely use Roman characters, such as some Asian-Americans. Election officials find that a decline in cursive writing leads to young voters more often printing their names in signature blocks; a California official said she "cannot compare a printed name to a signature."

Recommendations for signature verification

The Election Assistance Commission says that computers should be set only to accept nearly perfect signature matches, and humans should doublecheck a sample, but they do not discuss acceptable error rates or sample sizes.
The Election Advisory Commission says the first human check of a signature rejected by machines will average 30 seconds, and a sample of decisions to accept should be checked. They recommend all rejections should be checked by bipartisan teams who will average 3 minutes for the final decision to reject, which means 6 minutes of staff time, plus supervision time. The Commission also discusses the challenges of moving large numbers of envelopes without mixups from receipt, to machines, and various steps of verification, rejection, and voter notification to cure mismatches, as well as counting and logging the number of ballots at every step. They mention the extra security needed when voters send copies of identity documents to cure their signature rejection.
The Election Assistance Commission notes that signatures over 10 years old are another problem and recommends Hawaii's practice of inviting every voter to send a new signature. California researchers recommended that the public needs easy access to see the signature on file before mailing in ballots, to further maximize matches.
The National Vote at Home Institute recommends state-wide or regional centers for signature verification to increase transparency. and reduce the insider risks of temporary local staff,
though the Election Advisory Commission notes that shared equipment may not be consistent with local chain of custody requirements, and that public bidding may take months.

Blue shift

Blue shift is an observed phenomenon under which in-person votes trend towards the Republican Party, while mail-in votes, which are often counted later, trend towards the Democratic Party. This means that election day results can indicate initially indicate a Republican victory, but mail-in ballots later demonstrate a Democratic victory. This can lead observers to call into question the election legitimacy, when in fact, the election results are legitimate. Blue shift occurs because young voters, low-income voters, and voters who move often, are likely to vote by mail and are likely to lean Democratic.
One example is the 2018 California's 39th congressional district election. This was a hotly contested race for a seat in the United States House of Representatives, representing portions of Orange, Los Angeles, and San Bernardino Counties in Southern California. Republican Young Kim was running against Democrat Gil Cisneros. On election night, November 6, 2018, Kim held a lead of 3 percentage points and over 150,000 votes over Cisneros. However, as the votes were counted over the ensuing weeks, Cisneros overtook Kim in the vote count, and won the election.
Another notable example of blue shift was the 2018 United States Senate election in Arizona between Republican Martha McSally and Democrat Kyrsten Sinema. McSally led the vote count on election night, but Sinema ultimately won the election due to mail-in ballots. Democrats initially thought that they had lost that election, but ultimately won. In addition to these examples, blue shift has been documented in California, Pennsylvania, Oregon, and Ohio, among other states.
The phenomenon was first identified by Edward Foley of Ohio State University in 2013. He found that Democratic candidates are significantly more likely to gain votes during the canvass period, which is the votes counted after election night. This asymmetry did not always exist, as in the 20th century, as recently as the 1996 United States presidential election, Republicans and Democrats were both able to cut their opponents' lead during the canvass period. Foley conjectured that the 2002 passage of the Help America Vote Act accelerated the pronounced asymmetry of the blue shift phenomenon, because it required states to allow provisional ballots to be cast. He later found that the variation in the size of the blue shift is positively associated with the number of provisional ballots and the Democratic partisanship of the state in question. The growth in the persistent blue-shifted overtime vote began with the 2004 United States presidential election.
Foley has expressed concern that this phenomenon, along with difficulties in conducting an election during a pandemic, could lead to "a perfect storm" in the 2020 United States presidential election. This concern is particularly pronounced due to the fact that incumbent president Donald Trump has not stated whether he will accept election results.

Other challenges

In the case of all-postal voting, or a high proportion of postal votes, there cannot be traditional "Election Night" news coverage in which the results are delivered within hours after polls close, as it takes several days to deliver and count ballots. As a result it may require several days beyond the mail-in deadline before results can be publicized.
Postal voting depends on the viability of the postal service. As of early 2020, the U.S. Postal Service has "a negative net worth of $65 billion and an additional $140 billion in unfunded liabilities." This financial crisis has become more pressing amidst the coronavirus pandemic, as the $2 trillion economic stimulus package did not include money for the postal service. As a result, the postal service—despite its widespread use for delivering food and medicine—may have to close in June, before the November 2020 presidential election.

Alternatives

An increasing number of states in the US now allow drive-thru voting. In the process voters leave their absentee ballots in a drop box at designated locations. Some locations allow drop-off voting 24/7.
A National Task Force on Voting by Mail, organized by the conservative Public Interest Legal Foundation, says drop boxes need 24/7 video monitoring for security, and ballot collectors should not be allowed to drop off ballots from large numbers of voters.
Many states provide voters with multiple ways to return their ballot: by mail, via in person secure drop boxes, and at voting centers where they can get questions answered, replacement ballots, etc. Oregon now has 300 drop boxes across the state in the weeks leading up to each election, and more voters now cast their ballot in person than by return mail. The term "vote at home" is starting to replace "vote by mail" for that reason. California's roll-out of vote-by-mail is incorporating voting centers as a key part of their effort. Anchorage's successful pilot included many drop boxes and some voting centers.
