U.S. Representative Bruce Braley was unopposed for the Democratic nomination; the Republicans nominated State Senator Joni Ernst in a June 3 primary election.[2] Douglas Butzier, who was the Libertarian nominee, died on October 14 in a single engine plane crash near Key West, Iowa. He was the pilot and the only person aboard the plane.[3][4][5] He still appeared on the ballot, alongside Independents Bob Quast, Ruth Smith and Rick Stewart. Ernst defeated Braley in the general election. This was the first open Senate seat in Iowa since 1974. Ernst was the first Republican to win this seat since Roger Jepsen in 1978. Joni Ernst's inauguration marked the first time since 1985 where Republicans held both United States Senate seats from Iowa.

Republican primary
The Republican primary was held on June 3, 2014. If no candidate won more than 35% of the vote, the nominee would have been chosen at a statewide convention. It would have been only the second time in 50 years that a convention picked a nominee and the first time since 2002, when then-State Senator Steve King won a convention held in Iowa's 5th congressional district to decide the Republican nominee for Congress. Having the nominee chosen by a convention led to fears that the increasingly powerful Ron Paul faction of the state party, led by Party Chairman A. J. Spiker, could have nominated an unelectable candidate.[21][22]
The convention was scheduled to be held on June 14 but was then moved to July 12. Republican leaders, including Governor Terry Branstad and U.S. Senator Chuck Grassley, as well as four of the candidates for the nomination, criticized the move. Candidates Sam Clovis, Joni Ernst, Matthew Whitaker and David Young signed a letter to the Republican Party of Iowa asking them to move the convention date back, saying that "Essentially gifting [Bruce] Braley an additional 30 days to campaign in a vacuum, while reducing our nominee's time to raise funds and campaign as the general election candidate by an entire month – only serves to strengthen Braley's viability". Spiker responded that the move was necessary to accommodate the 27-day period that the Iowa Secretary of State's office requires to certify the results of the primary.[23] Spiker reiterated his position in September 2013, rejecting calls for a vote by the central committee to move the convention date. He said that nominating a candidate before the primary had been certified would break state law, "which outlines that a ballot vacancy does not exist until the canvass is completed and certified."[24]
Secretary of State Matt Schultz was highly critical of Spiker, saying that "no political party should use the excuse of the final date of the statewide canvass to determine the date of its special nominating convention. Furthermore, to state that it is necessary to hold a special nominating convention after the conclusion of the state canvass is not only misleading, it is false."[25] Following efforts by members of the central committee to call a special meeting to move the date back to June, Spiker agreed and a meeting was held on September 23.[26] The central committee voted 16–1 to move the convention date back to June 14.[27] Statewide Republican leaders and activists and members of the National Republican Senatorial Committee believe that the real reason for the attempt to delay the convention was to give the Ron Paul faction time to organize an insurgent effort to push through a candidate they support, which could have even been Spiker himself or State Party Co-chair David Fischer.[22] The infighting has been traced back to the failure of the NRSC and allies of Governor Branstad and Senator Grassley to recruit a "top-tier" candidate for the race.[22]
Ernst received widespread attention for a campaign ad she released in March 2014 where she employed a tongue-in-cheek comparison between her experience castrating pigs and her ability to cut "pork" in Congress.[28][29] Many found the ad to be humorous[30][31] and it was spoofed by late-night comedians including Jimmy Fallon and Stephen Colbert,[32][33] while some found it to be in bad taste.[34][35] Before the ad aired, Ernst had struggled in fundraising,[36][37] and two polls of the Republican primary taken in February 2014 had shown her in second place, several points behind opponent Mark Jacobs.[38][39] After it aired, a Suffolk University poll in early April showed her with a narrow lead and a Loras College poll showed her essentially tied with Jacobs.[35][40][41][42] By May, she was being described by the media as the "strong front-runner".[43]
In May 2014, Roll Call reported that the Republican primary campaign had become a proxy for the 2016 Republican presidential nomination, with Mitt Romney and Marco Rubio supporting Ernst, Rick Perry endorsing Whitaker and Rick Santorum backing Clovis.[44] Jacobs, who had no such high-profile endorsements, ran as the "outsider".[45]
Ultimately, Ernst won the primary with 56% of the vote, negating the need for a convention.
