2. A Net gain in the 2023-2024 redistricting cycle nationally
Pending resolution in things like Wisconsin, I don't think they got this, though. Notionally, 4 seats have flipped from D-in-2022 to R-in-2022 (all in North Carolina, including NC-1), while only 3 seats flipped from R-in-2022 to D-in-2022 (the ones in Alabama and Louisiana, and also the Syracuse seat held by Brandon Williams). Suozzi was not shored up by so much that Zimmerman '22 would have won the new seat.
Presidentially this doesn't work either: there are four new Trump seats (three in North Carolina, this time excluding NC-1, along with the redrawn LaLota seat on Long Island) but only two new Biden seats (the black seats in Alabama and Louisiana). The median House seat
barely shifted at all (from Biden+2.1, in MI-8, held by Dan Kildee, to Biden+1.9, in VA-2, held by Jen Kiggans), but it shifted very slightly rightwards.
