An election took place on February 24, 2015, to elect the mayor of Chicago. The election was non-partisan and no candidate received a majority. A runoff election was held between the top two finishers (both Democrats) on April 7, 2015, and resulted in the reelection of incumbent mayor Rahm Emanuel. The elections were concurrent with the 2015 Chicago aldermanic elections.
Emanuel ran for reelection, seeking a second term in office. In the first round, Emanuel received 46% of the vote and Democratic Cook County Commissioner Jesús "Chuy" GarcÃÂa received 34%. Because no candidate received a majority, a runoff was held. In the runoff, Emanuel received 56.23% of the vote, winning the election. Garcia received 43.77% of the vote. 2015 was the first time the election advanced to a runoff since mayoral elections became non-partisan in 1999.
