Need him as a Senator. Big League.
Collins would make a great Senator. I think he would win but it is not a lock. The rats almost took the Governors with that horrible woman. So with tepid GOPe support for Collins if he knocks out Kelly Loeffler who knows.
This seems like a strange move for him.
As someone else on FR posted a couple of weeks ago ... leaving his House seat and top committee assignment to run for junior Senator from Georgia is like giving up your job as captain of a Navy destroyer to become a deck hand on a merchant ship.
