Impressive work!! So PVI-wise we get:
- TX at 7R in 2008, no change by 2020
- DS at 3D-13R in 2008, becoming 6D-3S-7R by 2020 (wow!)
- GV at 5D-1S-9R in 2008, becoming 7D-1S-7R by 2020
- AM at 3D-1S-7R in 2008, becoming 3D-3S-5R by 2020 (not as much change, interesting)
- RG at 7D-1R, becoming 6D-1S-1R by 2020
- LN stays at 6R obviously
So Republicans in DS and GV made what looked like effective gerrymanders back in 2010 but were completely swamped by the trends, and even with new gerrymanders in 2020 they can only hope to preserve the seats they kept. In AM it looks like the Republican gerrymander is still working to some extent, so I think the 2020 redistricting should see Dems gain quite a few seats. In RG it will be interesting if Dems can shore up the areas they're losing ground in, or if they'll just accept a swingy district to shore up their other incumbents.
