He graduated with a bachelor's degree in political science from the University of Charleston in 1982. He married Susan Ryder in 1984 and they have two sons. Gainer worked in the West Virginia State Treasurer's office from 1985 to 1989, was the budget director of the West Virginia Department of Energy from 1989 to 1991 and was national accounts representative of John Deere & Company from October 1991 through December 1992.
Political career
In 1992, Gainer ran for State Auditor. He won the Democratic primary with 63%, defeating Mark Anthony Manchin, son of former Secretary of State and State Treasurer A. James Manchin and uncle of current U.S. Senator Joe Manchin. He was unopposed in the general election and took office in January 1993, succeeding his father, Glen Gainer, Jr., who had served in the office from 1977 to 1993. Denzil Gainer, a cousin of Glen Jr., had served as Auditor from 1961 to 1972, when he died in office. Gainer was also unopposed in the elections of 1996 and 2000. In 2004, he was re-elected with 62% of the vote, beating Republican Lisa Thornburg. In 2008, he was re-elected with 99.94% of the vote, defeating write-in Constitution Party candidate Robert Ingargiola, who won only 295 votes to Gainer's 525,084. In 2012, he faced a strong challenge from State Delegate Larry V. Faircloth, but he was comfortably re-elected with 57% of the vote. In November 2013, Gainer announced that he was running for the United States House of Representatives in West Virginia's 1st congressional district against Republican incumbent David McKinley in the 2014 elections. His father ran for the same district in 1982, finishing third in the Democratic primary. Gainer, outraised and outspent by McKinley, ran a "grassroots campaign", emphasising the need for consensus and bipartisanship in Congress. In endorsing him, The Charleston Gazette praised his bipartisan efforts and noted his effectiveness in the Auditor's office, particularly his saving $145 million a year through "p-cards" that simplify small-scale state purchases. In the general election, McKinley defeated Gainer by a roughly two-to-one margin. In December 2015, Gainer announced that he would not be running for re-election to a seventh term in 2016. He said that 24 years as Auditor was long enough and he didn't want to become "stagnant" in the office. Gainer said that he would pursue work in the private sector after leaving office in January 2017. In April 2016, he announced he would resign in May, before the end of his term, to accept a job with a nonprofit group, which was later announced as being President and CEO of the National White Collar Crime Center, beginning May 15. Gainer had previously served as the group's board chairman for 18 years. Gainer was succeeded as Auditor by Lisa Hopkins, who had worked for the Auditor's office since 1999 and had served as general counsel and deputy commissioner of securities since 2001. She was appointed by Governor Earl Ray Tomblin on May 13 and she took office 2 days later.
