You can go all the way down to state and local level....the damage was so broad, and coming at the point of the 2020 Census having a major effect on district maps for the whole decade ahead. It’s hard to imagine that eight years later, this amount of damage has been done and could take twenty years for them to recover.
The redistricting in 2020 though 2022 is going to be a battle royale. They are saying that we gerrymander too much (whatever the means but I hear it all the time). I think they are jealous because they only have 500 districts that they can play with. When all your voters are in a 20 mile radius what can you do? But they will fight fight fight. They want the House anyway they can get it.
