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. This was the first open race for this seat since 1958. 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 2022[update], this was the last time a Democrat was elected to the U.S. Senate, or won any statewide race, in Indiana, and the most recent Senate election in which an elected incumbent was defeated in the primary. 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.
