Since the 1973 creation of the 40-district legislative map, the 17th District has always been anchored by the city ofNew Brunswick and Piscataway Township. The 1973 iteration of the district also included Franklin Township and Manville in Somerset County and Highland Park, Middlesex, Dunellen, and South Plainfield. In the 1981 redistricting, the two Somerset County municipalities were shifted to the 14th District while the 17th picked up the Union County city of Plainfield. Dunellen was removed under the 1991 redistricting, but Somerset's Bound Brook was added. As part of the 2001 apportionment, based on the results of the 2000 United States Census, changes were made which removed Bound Brook, Middlesex Borough and Plainfield City and South Plainfield borough and added Franklin Township, Milltown Borough and North Brunswick Township. Changes to the district made as part of the New JerseyLegislative apportionment in 2011, based on the results of the 2010 Census resulted in the removal of Highland Park.
Election history
After 20 years in office, John A. Lynch Sr. did not run for re-election in 1977, due to illness. Assembly Speaker William J. Hamilton ran for the vacant Senate seat and Joseph D. Patero and David C. Schwartz were the Democratic candidates for Assembly in a district that voted for Democrats by a 2-1 margin. After losing the support of the Middlesex County Democratic Organization, Assemblymember Angela L. Perun announced in March 1985 that she had switched parties and would run as a Republican in that year's general election, after having served two terms in office as a Democrat and having been a vocal opponent of the Reagan Administration. Piscataway mayor Bob Smith was given Perun's spot and the Assembly ballot, and he won election together with incumbent David C. Schwartz. Despite his confidence that he would win re-election if he chose to run, David C. Schwartz decided not to run for re-election in 1991 after seven terms of office, saying that he was reluctant to serve in the minority party in the new legislative term. Jerry Green took Schwartz's open seat in the general Election. Bob Smith was elected to his first Senate term in November 2001 to fill the seat vacated after Lynch retired. Jerry Green was relocated to the 22nd Legislative District in redistricting following the 2000 United States Census, and the two open Assembly seats were filled by Upendra J. Chivukula and Joseph V. Egan. Chivukula's election made him the first South Asian to be elected to the New Jersey Legislature and the third Indian American to be elected to a state assembly in the United States. Joseph Danielsen was sworn into the New Jersey General Assembly on October 16, 2014 to fill the vacant seat of Upendra J. Chivukula, who left office to take a seat as a Commissioner on the New Jersey Board of Public Utilities. Owing to Middlesex County's strong Democratic leanings, the 17th District has never elected a Republican legislator, only being briefly represented by one when Perun switched parties in 1985. Senators and Assembly members elected from the district are as follows:
