Democratic candidate Mike Revis on Tuesday flipped what had been a deep-red State House seat in Missouri by a 108-vote margin over his Republican opponent.

Revis defeated GOP candidate David C. Linton in the special election to replace Rep. John McCaherty, who left the office to focus on his run for Jefferson County executive.

President Trump won the heavily Republican district by a 61-33 margin in the 2016 election. There were three other special elections in the state on Tuesday night, all of which the Republican party defended. However, there were major net swings towards Democrats.

Revis' win is likely welcome news for Sen. Claire McCaskill (D-MO), thought to be one of the most vulnerable incumbents facing reelection this year in a state that Trump won by over 18 points.

“Representative-elect Mike Revis’s victory tonight will undoubtedly send another shockwave through the GOP as we continue to run the best candidates focused on addressing local issues and improving their neighbors’ quality of life,” Democratic Legislative Campaign Committee Executive Director Jessica Post said in a statement. “The DLCC continues to be impressed by our dedicated and talented slate of candidates, who have stepped up to run in these precedent-setting special elections."

This marks the 35th legislative seat nationwide that has flipped since Trump’s inauguration and the second just this year.
