Sorry but you don’t get to put Truman, LBJ and Nixon on a list of people who went from the Senate to the Presidency. Stopping off at the VP spot on the way changes everything. Especially Truman and LBJ who went directly from VP to president without an election, even though they did go on to win on their own, I know.
And Nixon in 68 was not running on his Senate record. He was Ike’s VP. That was his big name recognition card.
Very true.
