You left out Reagan ... Shot by a deranged lunatic. Did you leave out any others? You can’t claim a pattern unless you present ALL the data. I’m not saying you’re wrong, I’m saying your work is incomplete.
Bullshit. Statistical analysis admits the logical impossibility of polling ALL of a population. Trends are just that. Trends.
There are 4 murdered presidents. All 4 were killed by democrats, of some flavor. There are 7 attempts listed of non-fatal shots fired at them, or in close proximity to them, that are of common historical knowledge, and one attack by a crashed airplane. 6 of those attacks were by admitted leftists.
Reagan's attacker, Hinkley, was SAID to be a romantic loon. Based on what I've seen during the last year, I'd easily suspect that he was another spoiled Leftist basement dweller whose political beliefs did not fit the media profile. The Leftist media hated Reagan. Back then, they were still uncomfortable admitting that they wanted to see him dead.
Note that, for the last 13 months, the alphabet network didn't acknowledge the EXISTENCE of Antifa. Only in the last 10 days, with too many Youtube clips floating around, have they grudgingly mumbled that, maybe, a few fringe elements MIGHT be, possibly, perhaps, if you squint your eyes, a threat...
