LBJ was also an immoralist, like JFK and the Felon, using WH secretaries as his personal concubines. RATS are all scum, but put them in the Oval Office and they become sewer scum.
He was corrupt. Very, very corrupt. He would do almost anything for almost anybody, so long as it enriched and/or empowered him.
But LBJ had some standards. I don't think he ever sold out his country for campaign cash.
