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. This time, Mr. Begich benefited from a G.O.P. 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. Before Ms. Peltola, the last Democrat to represent Alaska in the House was Nick Begich Sr., Mr. Begich’s grandfather. Former Young aides called Mr. Begich deceitful and disloyal to their boss and chose to back Ms. Peltola instead.
