https://www.washingtonpost.com/opinions/2020/09/21/nightmare-ahead-imagine-damage-6-3-conservative-supreme-court-could-do/"A newly enhanced conservative court majority will continue to erode voting rights and rubber-stamp GOP voter suppression; before long they’ll probably declare nonpartisan redistricting commissions unconstitutional so Republicans can crank gerrymandering up even higher."Does anyone realize the party this would hurt the most after 2020 would be the Republicans? Imagine if CA, NY, NJ, WA, VA, CO, MN, IL maps the Democrats could draw. They could easily make NJ a safe 10-2 instead of a competitive one and make NY 2, 11 deep blue leaning districts. That doesn't even get to what they could do in Cali..possibly something along the lines of 49-4.
The GOP would have FL, GA. NC they may control but the Supreme Court there will probably halt anything absurd this time. TX we'll see what happens in the state house. Chance Dems get the AZ legislature this year which would negate any court decision and then could do a mid decade redraw if they get the Governor in 2022.
PA, MI, WI are split and the PA Supreme Court could give the Dems a pretty friendly map.
Overall it seems like Dems would probably gain seats. They would lock in all their recent gains in NJ, VA and probably gain another 6-12 seats out of the rest.
