Gov. Chris Sununu of New Hampshire, a Republican, said on Wednesday that he would not run for re-election in 2024, opening up a seat in a battleground state that Democrats will be eager to take.
Mr. Sununu made the announcement in an email to supporters.
“This was no easy decision as I truly love serving as governor,” he wrote. “Public service should never be a career, and the time is right for another Republican to lead our great state.”
Almost immediately, Chuck Morse, a Republican who served as president of the New Hampshire Senate and lost a primary for U.S. Senate last year, announced that he would run for the Republican nomination to fill the seat — praising Mr. Sununu’s economic policies and saying he was running “to build on those successes.” Another Republican, former Senator Kelly Ayotte, also hinted that she might jump into the race.
Two Democrats — Cinde Warmington, a member of the New Hampshire Executive Council, and Joyce Craig, the mayor of Manchester — had already begun campaigns before Mr. Sununu bowed out.
The vacancy will be a big opportunity for the Democratic Party, which has won the last five presidential elections in New Hampshire and holds both of the state’s Senate seats.
Like some other Northeastern states, New Hampshire has often voted for Republicans for state offices despite leaning blue in national elections. But Democrats flipped two such governorships last year — in Maryland and Massachusetts — after popular, moderate Republicans in the same mold as Mr. Sununu retired.
“No matter which MAGA candidate becomes the nominee, the D.G.A. is eager to hold them accountable to flip this seat and elect a new Democratic governor who will at long last fix the biggest issues impacting working families,” the Democratic Governors Association said in a statement.
Mr. Sununu, 48, is serving his fourth two-year term as governor, having been re-elected last year by more than 15 percentage points. He recently decided against two opportunities to run for higher office: He declined to run in last year’s Senate race, and for president in 2024. His next steps are unclear.
