Please don't fall for this left-wing meme. Kennedy was killed by one of their own, Oswald, who was a Cuba loving, commie thug/fanatic (redundant, I know). The left/liberals needed to start this conspiracy-theory crap to try and blame anyone else for the "fall of Camelot" - and help keep that myth alive at the same time. Let's all try and see it for what it is and not help them keep this BS spreading.
No telling what Johnson would have said if he'd lived longer, but Lady Bird had more class than Jackie, and wouldn't have been recorded spreading rumors.
Would`nt surprise me in the least if LBJ was involved.
