Almost every assassin in our history has turned out to be a left-wing crazy of some sort. John Wilkes Booth was a copperhead/confederate sympathizer if not an agent, Lee Harvey Oswald (who I include even though he didn’t do it) was a traitor who lived in Soviet Russia and was pro-Castro. RFK’s assassin was a Palestinian terrorist.
Booth was a lot of things but he was not a left winger. LOL.
