South Dakota’s lone member of the U.S. House of Representatives is seeking to trade in his Washington, D.C. office for the governor’s office in Pierre.

GOP Rep. Dusty Johnson entered the race Monday for South Dakota governor, as Gov. Larry Rhoden (R) has yet to announce whether he will run for reelection. “South Dakota is a special place where hard work, conservative common sense and firm handshakes are a way of life,” Johnson says in an ad posted on YouTube.

Rep. Dusty Johnson (R-SD) could face a strong primary challenger in the 2026 midterm elections from his home state’s attorney general. South Dakota’s at-large congressional seat has been held by Johnson since 2019.
