For sure, I was raised in The South, and he was not liked by a lot of Southern DEMOCRATS. That's why he was in Texas in the first place. Having just come from Miami, IIRC, he was on a campaign swing through The South to shore up his sagging support there.
When I was a paperboy in 1968-1972, I had a customer that refused to take a Kennedy Half Dollar from me as change for paying his bill. Kennedy was hated by a lot of people and they celebrated his death. But the MSM will never show or tell about such things....................
I think everybody who was around in the Sixties or Seventies heard the story of the school where the principal announced over the public address system that Kennedy had been shot and the students cheered.
After all the wild stuff I hear on the internet, I wonder if the story was true. I do remember somebody cheering when they announced that Reagan was shot, but she was an idiot.
In the South Kennedy’s approval fell from 60% to 44% after a civil rights speech. But nationwide Kennedy did have the highest approval rating of any president since polling became a regular thing after WWII.
The problem with the conspiracy theories is that they assume that Kennedy was a “good guy” who was going to turn on the Deep State. He was pretty much Deep State himself, though a lot of people don’t want to believe that.
