The 2012 United States Senate election in Indiana took place on November 6, 2012, concurrently with the U.S. presidential election as well as other elections to the United States Senate and House of Representatives, and various state and local elections.
Incumbent Republican U.S. Senator Richard Lugar ran for reelection to a seventh term, but was defeated in the primary by Tea Party-backed Richard Mourdock. U.S. Representative Joe Donnelly, a Democrat from Indiana's 2nd congressional district, was unopposed in his party's primary, and then defeated both Mourdock and Libertarian Andrew Horning in the general election.
As of 2024, this is the last time Democrats won any statewide election in Indiana, and the most recent Senate election in which an elected incumbent was defeated in the primary.[a][2] This election is also the most recent time a party would flip a Senate seat in a presidential election year without carrying the state in the concurrent presidential election.[b] This is also the last time that a party flipped a Senate seat in a state that flipped against them in the simultaneous presidential election.
