If these margins are realized, the GOP gains in the House might not exceed 11.
LOL, are you kidding us. Republicans don't need a single District Win in New York State to flip the House. There are enough Districts East of the Mississippi River to give Republicans a clear cut House Majority.
Sure but if Democrats are winning districts that narrowly voted for Biden in New York it's probably not just a thing in the state but means Republicans aren't making huge gains in swing districts across the country.
