I've been talking about this for the last six months.
Republicans did not abandon their gerrymandering push out of ethics. They realized that they'd fucked up to such an extent that their 2024 coalition no longer exists, and they can't accurately project where they will have strength in 2026. Therefore, the gerrymandering they have done has largely worked against them.
That'll happen when you're elected on affordability and don't do jack shit to fix the cost of living.
