If you go from 8 seats down to 7, then the districts have to expand. Unless someone retires, 2 incumbents have to run against each other.So now Democrats are bragging about gerrymandering? I remember when they thought it was a bad thing. Now it’s simply called “redistricting“.
With that said, you're right. They should appoint an independent commission to draw the maps. I wouldn't trust either party that has complete control to do gerrymander the maps.
