I can only think of three that I would definitely want to see back.
Chuck Grassley
Jim Jordan
Ron Johnson
I know there are more good ones than these three, but off the top of my head these are the best.
None of the congresscritters from my state, Texas, should be allowed to return.
None, clean house, set term limits, make it illegal for anyone in government to accept money from any corporation, and change the rules so that once their time is done they can no longer benefit and start fresh.
