One more LBJ POD, that's all.
According the the Polish-Lithuanian Genocide, the Secret Service refused to allow Johnson to speak on college campuses in 1968, due to his extreme unpopularity with university students.
What if LBJ appears on a college campus and gets assassinated by an anti-war protester in, say, the early April of 1968, just a few days after
1. Kennedy has joined the race.
2. He's announced he's suspending all bombing of North Vietnam.
3. He's decided not to run for a second (full) term.
What happens in America?
NOTE: Say a few days after MLK is assassinated in Memphis. Let's just say that the shooter is white, so we don't have a race war on our hands, since that's not what I really want this discussion to be about.
