The Indianapolis mayoral election of 2007 took place on November 6, 2007. Voters elected the Mayor of Indianapolis, members of the Indianapolis City-County Council, as well as several other local officials. Incumbent Democrat Bart Peterson was seeking a third term. Republicans nominated former Marine Greg Ballard to run against Peterson. In what was called, "the biggest upset in Indiana political history", Ballard defeated Peterson 51% to 47%.[1]
