Plain and simple, Senators make lousy Presidents.
GHW Bush was never a Senator.
PSSSSTTT! I’ll let you in on a little secret... George was Never a Senator... unless it was years and years before. He is credited with saving the Republican Party during the Nixon Resignation and refused a promised VP Nomination in return for the Ambassadorship to China. The Chinese Greatly Respected and Honored both He and His family during that time! The Chinese Respect is from First Hand Knowledge!
Bush was a senator? Where? When?
