The 2018 United States Senate election in Indiana took place on November 6, 2018, along with other elections to the United States Senate and House of Representatives and various state and local elections. Incumbent Democratic U.S. Senator Joe Donnelly sought re-election to a second term, facing Republican businessman and former state representative Mike Braun and Libertarian Party nominee Lucy Brenton. Braun defeated Donnelly in the general election by a margin of 6 percent.

In 2017, Politico described the race as "possibly the GOP's best opportunity to seize a Senate seat from Democrats" in the 2018 elections.[1] The primary election was held on May 8, 2018.[2] In October 2018, RealClearPolitics rated the race a toss-up between the Democratic and Republican nominees, with the Libertarian receiving a poll average of 6%.[3]

Background

In 2012, Joe Donnelly was elected to the Senate with 50% of the vote to Republican nominee Richard Mourdock's 44%. In the 2016 presidential election, Republican nominee Donald Trump won Indiana with about 56.5% of the vote to Democratic nominee Hillary Clinton's 37.5%.[4][5]
