'The tides are turning': Shockwaves as Dem scores double-digit win in red district

It's a double edged sword during a wave election. Gerrymandering is predicated on putting a plurality of Your Team reps in seats with single digit margins and Their Team reps in seats with oversized 80/20 margins.

If Your Team drops by ten points in the polls, suddenly all your "Safe" seats aren't. Look at what happened in Alabama during the 2018 Senate Race.

The catch is that the incoming majority then has an opportunity to rewrite the districts in their own favor - break up the consolidated 80/20 seats and spread those voters around. If they don't do that (as Dems failed to do in '07/'09 or '18/'20) then normal election seasons favor Republicans and you get a '10/'14/'22 reversion to the mean.

Do you mean 2020? Because the only thing getting throttled in 2024 was Dems.

There was a few week period of interia between when Biden had dropped out, and before Harris had done anything to define herself as candidate, where most people were proceeding on the assumptions we could make based on her 2020 primary run. But then she said "fuck all that" and said she was just going to do the exact same things as Biden.
