U.S. Senator before election

Tom Cotton

Elected U.S. Senator

Tom Cotton

This election was strange because there was no person from the Democratic Party in the election. This was because the only person in their primary election, Josh Mahony, withdrew and it was too late for anyone else to be in the primary.[1] Only Cotton was in the Republican Party's primary election.
