Gerrymandering is completely out of control. Mostly R's are locking-in their wins for the foreseeable future.

I don't think it's a D/R thing in particular. He's completely corrupt by WV coal and other corporate interests paying him to be an insurgent DINO to do their bidding. Sinema is clearly a nutter and possibly corrupt too. The D's and R's also contain too many corrupt, plutocrat sycophants to name individually here. The system is what's broken, and it's doubtful it can be fixed from within.
