U.S. senator before election Joe Donnelly Democratic Elected U.S. Senator Mike Braun Republican

This was one of ten Democratic-held Senate seats up for election in a state won by Donald Trump in the 2016 presidential election. 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]

Instead of running for a second senatorial term in 2024, Braun campaigned successfully to become Governor of Indiana.

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]
