Considering LBJ had a heart attack in the 1950s, I question just how ambitious he truly would have been at that point. This is the same guy that chose to step down rather than run for re-election.
Of course I suppose that’s more fodder, because some could say that LBJ was offered a deal to step down, and not let the truth of his involvement in the assassination to come out in exchange.
I don’t know if it will ever be proven, but most Texans know that LBJ was among the most corrupt, cutthoat, and ruthless politican in the history of this state.
