This is what happened in Pennsylvania. Once the CDs were drawn iaw the Commwealth's constitution (compact and not splitting towns, cities and municpalities), our CD went from 13R-5D to 9R-9D. We still have districts that favor Rs to a more or lesser extent and so will VA.

Dick Cranwell was forced out when the Republicans moved his district line across the street from his house. He was pumped into a seat already held by a Dem. dick was ready to retire anyway but still...

The lines here for Congressional seats was also redraw by the courts which put McEachin in.
Bobby Scott's district used to run from Hampton to across the James (peanut country) then back across the river into a poor white neighborhood in Richmond, Oregon Hill. At one point I called Tom Bliley'#s Office to get help with my GI Bill - I was rudely told I wasn't in his district. I had to call back (no real internet at the time) and was shocked that I was in Bobby's district. Got the check 3 days later.

We have to fix it so a catastrophe like Trump never happens again.

They will fuck it up!

"help the Democrats", neglecting to note that this is a fix to GOP-gerrymandering that was purposely done to unfairly skew seats their way.

I am hoping that we can eventually get our state legislative seats fixed here in PA. The effort to get a fairer system of drawing lines apparently requires a change in the state Constitution and I think ballot initiatives, etc.
