Congress

In 1996, Pappas ran for the House of Representatives in New Jersey's 12th congressional district. The incumbent, Republican Dick Zimmer, gave up his seat to run for the U.S. Senate that year. Pappas won the Republican primary, defeating State Senator John O. Bennett and Assemblyman (and future 7th district Representative) Leonard Lance. He then won the general election against Lambertville Mayor David DelVecchio.

Unlike most New Jersey Republicans, Pappas was a staunch conservative. His congressional service included pushing for a stronger national defense, the elimination of the capital gains tax, advocacy for small business, securing the release of the battleship USS New Jersey to the state of New Jersey as a museum, and resurrecting the controversial "Star Wars" national missile defense.^{[citation needed]}

He was a strong supporter of the impeachment of Bill Clinton, and his infamous singing of "Twinkle, Twinkle, Kenneth Starr" on the House floor^[3] contributed to his defeat by Rush Holt in 1998.^[4][5]

In 2000, Pappas unsuccessfully sought the Republican nomination for his old congressional seat, losing a highly contentious primary to the more moderate Zimmer by 62 to 38% margin. Holt narrowly defeated Zimmer in the general election to retain his seat.

State Senate campaign

In 2021, Pappas announced that he would be running for the Republican nomination for State Senate in New Jersey's 16th legislative district. The incumbent, Christopher "Kip" Bateman, a moderate Republican who barely won re-election in 2017, decided to retire. The 16th district had previously been a safe Republican district, but after re-districting in 2011, it became a swing district after the removal of Bridgewater and the addition of Princeton. Both of its Assembly seats flipped from red to blue during the 2010s decade. In the early stages of the race, he again competed against Zimmer, who, like Pappas, was also making his first run for political office in over a decade. After Pappas won the organization line for Somerset County, a large part of the 16th district, Zimmer dropped out of the race.^[8] Pappas won the Republican primary in June 2021.^[9][10][11] He lost the general election to Democrat Andrew Zwicker, the district's state assemblyman in November 2021.
