On Thursday, President Trump teased reporters that he would be making a major announcement at tonight’s rally in West Virginia. The New York Times reveals Gov. Jim Justice of West Virginia will switch from Democrat to Republican.

New York Times reports:

Gov. Jim Justice of West Virginia, a Democrat who was elected last year even as President Trump carried the state by 42 points, is expected to announce Thursday night at a rally with Mr. Trump that he is changing parties, according to three sources familiar with the plans.

Speaking to reporters in the White House Thursday, Mr. Trump promised “a very big announcement” at a gathering in Huntington, W.V., that is expected to draw thousands of supporters from across Appalachia, a region that gave Mr. Trump some of the largest margins of his election.

Mr. Justice, a billionaire coal and real estate magnate, ran as a conservative Democrat and declined to endorse Hillary Clinton in 2016. But even as West Virginia has become a reliable Republican state in presidential elections and further down the ballot, a handful of Democrats have still been able to win office.
