On the plus side Johnson achieved a great many domestic gains. (Unmatched by any subsequent President) These include Medicare, Medicaid, the Civil Rights Act, and the Voting Rights. When he left office the country was divided over Vietnam, yet the budget was balanced and unemployment was at historic lows. With time both his supporters and his critics will be taking a more balanced view of his Presidency. Horse Crap!!! He will forever go down in history as a piece of garbage.
Perhaps, in the future, the Vietnam Wall will be renamed "Johnson's Legacy".
If you thought Johnson was a hawk you should have seen Goldwater. There simply were very few doves in that period. There were two who voted against the Gulf of Tonkin Resolution (not unlike Barbara Lee) and they were not very popular. The Vietnam War was the work of a flawed foreign policy that predated Johnson. It was maily Henry Lodge's pushing for the coup against Diem that forced American's hand in Vietnam. Don't tell me you considered Lodge a Democrat.
