Let me get this in before the flames begin...
LBJ did more for Civil Rights than any other President since Lincoln. His work in Congress brought electricity to rural America where companies deemed it unprofitable. His downfall was Vietnam, a dirty little war handed down to him from Eisenhower via Kennedy. LBJ was not faultless on Vietnam, but he was given some very bad intel during the war from Westmoreland and very bad advice from McNamera. Just imagine what could have been accomplished in America if Ike had never entered the conflict.
