Syracuse, N.Y. – Democrat John Mannion has defeated Republican Rep. Brandon Williams in one of the nation’s most hotly contested House elections, boosting Democratic hopes of controlling at least one chamber in Congress. Mannion took the stage at his election night party in Syracuse and declared victory shortly after 11 p.m. Williams has conceded.

Mannion carried 53% of the vote to Williams’ 46% in the closely watched race, preliminary tallies from Tuesday’s election show.

Democratic state Sen. John Mannion defeated incumbent GOP Rep. Brandon Williams, flipping his upstate New York district. Williams swept into office on New York’s “red wave” in 2022 but was considered one of the most vulnerable members this year.
