Off the top of your head, which do you think are generally more corrupt, Governors or Congresscritters?
Q: Why do we hear so much more about Governors, then?
A: House and Senate Ethics Committees.
My rule of thumb these days is that a whisper of an accusation against a governor raises my doubts, a whisper of an accusation against a Congressperson raises my suspicions. Unfair? Only if I don't harden my opinion before the facts are in. It's a good first estimate.
