By my current count, Republicans have a majority on 26 U.S. House of Representatives state delegations. 3 state delegations (Mich., Minn., and Penn.) are evenly split. And 1 state delegation (Iowa) is not yet determined.
Michigan is split: 7-to-7;
Minnesota is split: 4-to-4; and,
Pennsylvania is split: 9-to-9.
Iowa has 4 seats. 2 seats are now Republican; 1 seat is Democratic. And 1 seat (Iowa-2) is not yet called, with 89% reporting, the Republican leads by 48 votes.
10 House seats are not yet called:
CA-21: 99% reporting, Republican leads Democratic-incumbent by circa 1800 votes.
CA-25: 99% reporting, Republican-incumbent leads Democrat by circa 400 votes.
CA-39: 99% reporting, Republican leads Democratic-incumbent by circa 4000 votes.
[Why hasn’t CA-39 been declared?]
Iowa-2: 89% reporting, the Republican leads by circa 50 votes.
NY-2: 83% reporting, the Republican leads by circa 40,000 votes.
NY-3: 85% reporting, the Democratic-incumbent leads by circa 20,000 votes.
NY-11: 85% reporting, Repub leads Democratic-incumbent by circa 37,000 votes.
NY-18: 79% reporting, the Democratic-incumbent leads by circa 10,000 votes.
NY-19: 85% reporting, the Democratic-incumbent leads by circa 17,000 votes.
NY-22: 84% reporting, Repub leads Democratic-incumbent by circa 23,000 votes.
Louisiana-5 will advance to a run-off: top-2 Republicans only. So it will be an R seat.
House is now 219 D to 206 R. If the leads above are maintained, the final composition of the House will be: 222 D to 213 R. The Democrats started with 235 seats. So 222, is a drop of 13 seats. This will be the narrowest House majority since 2001.
