Elections
2014
On October 15, 2013, Sullivan announced his candidacy for the U.S. Senate seat held by Democratic incumbent Mark Begich in the 2014 election. He was endorsed by the Club for Growth. Begich had narrowly defeated longtime incumbent Ted Stevens in the previous election. Stevens had filed for the election in 2009 following his exoneration, and was widely expected to win, but died in a plane crash on August 9, 2010. This left the race for the Republican nomination wide open.On June 10, 2014, Sullivan offered Begich the Alaska Agreement. This was a modified version of the People's Pledge. This tactic had previously been used in the Massachusetts 2012 U.S. Senate race between Elizabeth Warren and Scott Brown to drastically limit outside, third-party spending. Begich rejected the agreement. According to Ballotpedia, outside spending in the race hit nearly $40 million.
Despite former Governor Sarah Palin's late-race endorsement of 2010 party nominee Joe Miller, Sullivan won the August 19 Republican primary with 40% of the vote to and Miller's 32% and Treadwell's 25%.
On November 12, 2014, the Associated Press and CNN declared that Sullivan had defeated Begich in the general election by about 8,000 votes—48.6% to 45.4%. At the time, there were approximately 31,000 votes left to count and Begich refused to concede. Begich eventually conceded on November 17. Final results showed that Sullivan won by 6,014 votes out of 282,400 cast, 47.96% to 45.83%.
2020
In the 2020 election, after running unopposed in the Republican primary election, Sullivan faced independent candidate Al Gross, an orthopedic surgeon and former commercial fisherman who had been nominated by the Alaska Democratic Party. The race was considered "unexpectedly close," with some polls indicating that the two candidates were neck-and-neck. Gross touted his "deep roots" in the state and published several campaign videos that received national attention. In addition to the Democratic Senatorial Campaign Committee's funding of Gross's candidacy, Gross reportedly did "an excellent job fundraising", outraising Sullivan between July 1 and the end of September 2019.While the race was considered "too early to call" for several days after the November 3 election, Gross called Sullivan to concede on November 13. Ultimately, Sullivan defeated Gross 54% to 41%, with Alaskan Independence Party nominee John Howe receiving nearly 5% of the vote.
