You’re completely right, and I won’t be at all surprised if the violent nutjob is as much a bigot and xenophobe who thought Trump wasn’t Nazi enough to be trusted.

I’m just pointing out that his party registration isn’t necessarily an indication of his personal beliefs. Maybe he’s a psychotic centrist who wants a more moderate Republican candidate, or he’s a delusional progressive who thought the world would be better without Trump in it. Maybe he was a rape victim seeking vengeance, or a failed applicant from The Apprentice.

We don’t know why he tried to kill former President Trump. There are a lot of possibilities, and his party affiliation may or may not be relevant.
