Ah! There ya go. I was trying to think of a different person for each. GHWB does fit each one.
See post 1071.
Maybe not. GHWB was never a senator, but he did serve I the House.
The 1970 United States Senate election in Texas was held on November 3, 1970. Incumbent Democratic U.S. Senator Ralph Yarborough was defeated by former Representative Lloyd Bentsen in the Democratic primary. Bentsen then defeated Representative George H.W. Bush in the general election.

Dubya was never a Senator. I don’t believe Poppy was either.
