“It’s been the honor of my lifetime to serve South Dakota in Congress and to have the opportunity to help secure the southern border, cut trillions in wasteful government spending, and reclaim the fight against the Chinese Communist Party,” Johnson said in a statement.

“But it’s time for a new chapter—a chapter that drives South Dakota to a brighter future where we build better schools and safer communities, a chapter that governs with conservative principles to create new jobs, new businesses, and new opportunities in every community, and a chapter where being a workhorse, not a show horse, still means something,” he added.

Johnson, who is chairman of the Main Street Caucus, will forgo reelection for another term in South Dakota’s at-large congressional district in the 2026 midterm elections.

South Dakota Attorney General Marty Jackley is seriously considering a bid for the House seat, which is rated “solid Republican” by the nonpartisan Cook Political Report. The last time a Democrat held the seat was in 2011.

Johnson joins five other House Republicans running for governor of their home states: Reps. Randy Feenstra (R-IA), John James (R-MI), John Rose (R-TN), Byron Donalds (R-FL), and Andy Biggs (R-AZ). Other Republicans, including Reps. Nancy Mace (R-SC) and Ralph Norman (R-SC), are also speculated to be announcing a bid for governor.

The House has thin margins, with Democrats only needing a net gain of three seats to take back the majority and break up the GOP trifecta.
