There's about 8 seats that were within 5% and Beto won 6 of those. If all flipped and nothing else, that'd be a tied chamber.
Assuming swings of 10%, that'd be another 9 seats that could be caught in a wave. Granted, Cruz won 6 of them but the margins were within 4%.
I don't have PVIs calculated, but I hope the Texas Democratic Party is hitting the ground running
DRA has the entire state house map for all states.
This is probably the best map the GOP could have drawn for this decade. 2.5 R seats. Would have started as a D gerrymander lol. This is with perfect hindsight. Theyc ould have also drawn 2 more Mccain districts with the rest of Dallas that would easily flip by now.
