As vote counting from the November 5 election continues, Republicans are on the brink of securing control of the U.S. House of Representatives, having won 211 seats and needing just seven more for a majority. Edison Research projects that Republicans have already flipped the U.S. Senate, while key races remain uncertain in competitive districts, particularly in Western states. Democrats have made notable gains, flipping two significant seats in New York, but still face a tough battle with 24 races undecided. The outcome of these races will determine the extent of power Republicans will wield to advance President-elect Donald Trump's agenda, which includes tax cuts and energy deregulation. With Republican control of the Senate established, they are positioned to confirm Trump's cabinet and judicial nominees, although they lack the supermajority needed for fast-tracking legislation. The political landscape remains dynamic as both parties strategize for the final outcomes in these critical races.
