Don’t know what Temu means, but don’t sell yourself short at all, Zach. I’ve been super-impressed with your work, your command of the map and of voting patterns. Congratulations on an incredible year.

Florida's new congressional map cost Democrats a seat in 2026
On the old 2022-24 lines, this year's House vote would have elected 9 Democrats. The new map held them to 8, with 5 seats decided by under a point (FL-7, 9, 13, 26, 27)

Resharing: working on a more formal measure of overperformance, but preliminarily @BlueDogBark backed challengers ran 4.6 pts better than other Dem challengers after controls. Bobby Pulido’s +43 in TX-15 was truly extraordinary.

Despite a far stronger national environment for Democrats, Independent Dan Osborn's second run for Senate did not end up different than his first.
He trails projected winner Pete Ricketts by 6.8%, a worse margin in 2024 (6.7%).
