Begich Defeats Peltola in Alaska, Flipping House Seat for Republicans

Nick Begich III, the Republican son of a prominent liberal political family in Alaska, has defeated Representative Mary Peltola to win the state’s sole House seat, according to The Associated Press, ousting one of the nation’s most vulnerable Democrats and adding to Republicans’ slim House majority.

The victory, announced on Wednesday, more than two weeks after Election Day, was a comeback of sorts for Mr. Begich, an Anchorage native and businessman who was endorsed by the right-wing House Freedom Caucus and who had challenged Ms. Peltola in 2022 but fell short. Back then, Republicans split their votes between him and former Gov. Sarah Palin, allowing the Democrat to prevail in Alaska’s unusual ranked-choice voting system. This time, Mr. Begich benefited from a G.O.P. that united behind him.

Ms. Peltola, the first Alaska Native elected to Congress, staked her campaign on her working-class appeal and presented herself as a solutions-focused pragmatist fighting for the state’s future. She first won the seat in a special election after the death in 2022 of Representative Don Young, the longest-serving Republican in the House. Before Ms. Peltola, the last Democrat to represent Alaska in the House was Nick Begich Sr., Mr. Begich’s grandfather.

During his first run for Congress, the younger Mr. Begich, who once worked for Mr. Young, drew a backlash from Republicans for challenging the congressman in a primary shortly before Mr. Young’s death at the age of 88. Former Young aides called Mr. Begich deceitful and disloyal to their boss and chose to back Ms. Peltola instead.

That was not the case this year. The party united behind Mr. Begich after his top Republican rival, Lt. Gov. Nancy Dahlstrom, withdrew from the race after placing behind him in the late-August primary. Ms. Dahlstrom had the backing of both former President Donald J. Trump and Speaker Mike Johnson.

Mr. Begich has said he wants to decrease federal spending, a touchy subject in Alaska, where the U.S. government employs more than 16,000 people and federal spending pays for almost half the state’s budget.
