RICHMOND, Va. – Republicans have won at least 50 seats in the Virginia House, ensuring at least a tie with Democrats who had fought to retain control of the chamber.

Several races are still too close to call, but the GOP also declared victory in some of those, with party leaders saying they were confident they had flipped control of the House. House Republican Leader Todd Gilbert issued a statement Wednesday, saying Republicans have “clearly won six seats previously held by Democrats,” giving Republicans the majority.

House Speaker Eileen Filler-Corn isn’t conceding the loss of the Democratic majority in the House of Delegates, despite a Republican surge to a 52-48 seat advantage Wednesday morning. Filler-Corn, D-Fairfax, said she is waiting for final results in at least two House races – one in Hampton and the other in Virginia Beach – in which the margin of Republican victory was less than 1 percentage point of the vote in elections on Tuesday.

Eight of the Republican incumbents who won re-election were uncontested, while two of the seats flipped were the last of the predominantly rural districts held by Democrats. In some of the races that have yet to be formally called, the GOP has already declared victory while party leaders voiced confidence that they had gained control of the House.

Virginia Republicans are celebrating widespread success, topped off by Republican businessman Glenn Youngkin’s victory in the gubernatorial race, Winsome Sears becoming the lieutenant governor, and Jason Miyares elected as attorney general, beating  two Democratic challengers and two-term incumbent Mark Herring.
