My personal opinion is that LBJ was a better President than Kennedy ever would have been. It is forgotten now, because of LBJ's connection with the Vietnam debacle, exactly how "progressive" he was. The Civil Rights legislation that he shoved through Congress with a mixture of carrot and stick was beyond the skill of the Kennedys to get passed. It required a southern Democrat of LBJ's manipulative skill.........
LBJ also was determined to alleviate poverty, white and black, in the United States.......and worked tirelessly towards that end. Unfortunately, Vietnam consumed an ever-increasing portion of his resources and energy.......LBJ was a Texan, he couldn't back down. A tragic hero in the classic sense, a good man destroyed by a events that revealed a deep, personal flaw.
John and Robert were essentually the new power generation in a massively corrupt dynasty.......old Joe was an incredible SOB. I think a few more years in power, and the shine would have really been off the Kennedy family........a shame, though, that Teddy, who is SUCH scum, is the only one surviving........
