I never thought of it that way--thanks for the insight.
I was fifteen at the time & even then I could see that Lyndon Johnson owned the media so thoroughly that it would have made FDR jealous. “Doing what JFK would have wanted done” was the mantra in the WH press room.
Barry Goldwater already possessed a distinguished resume but the talking heads turned him into little more than a troublemaker (read his online bio - he was amazing).
The media didn’t turn against LBJ until about the fall of 1967 - Vietnam, antiwar protests, counterculture, etc.
