This is absurd! Absent Vietnam, LBJ would have been handily reelected in 1968. His own party activists in the Chicago riots and Nixon's "secret" plan to end the war beat the Democrats. Very little that the "journalists" of the left say is without major untruths, necessary to their views and anti-American retoric.
I could be wrong, but isn't there a real quote by lbj, something like, "We'll have the niggras in our back pocket for generations". Like I said, I could be wrong.
