West Virginia’s Governor is gearing up to challenge Senator Joe Manchin for his seat in 2024. Republican Jim Justice filed Thursday to run for U.S. Senate. Justice was a Democrat between 2015 and 2017, when he announced a party change at a rally joining then-President Trump. Democrat Manchin has not said yet whether he plans to run for re-election, but his seat is on relatively wobbly ground. The moderate has blocked some of Biden’s agenda in the Democratic-controlled Senate, such as the Build Back Better act, and has been against calls from his party to pass voting rights legislation and others.
