Because it's a secret vote, we don't know exactly who voted for Thune to be the Senate Majority Leader, but we know a few of his public supporters.

Senator John Thune has been in Congress for nearly three decades. He was first elected to the US House of Representatives in 1996.

Republicans have elected South Dakota senator, John Thune, as the next Senate majority leader replacing Mitch McConnell as leader of the GOP caucus. During the second round of secret ballots held behind closed doors, Thune beat Senator John Cornyn by gaining the majority support of GOP senators. The final vote between Thune and Cornyn was 29-24.
