I really don't think so. Liberal Democrats hate guns. And I don't think it's any kind of communist/anarchist/lefty/etc either because I think someone who's serious enough to want to kill Trump would also be serious enough to have more important organising to do than a suicide mission trying to shoot trump at a trump rally. I think more likely it's someone who doesn't have particularly conventional/left-wing political motivations. Maybe someone who's quite mentally ill or otherwise someone with quite out-there views.
That would be insane but also definitely the best case scenario for us. If that's the case that news had better break out quick before this is used to justify further repression of the left.
Being a liberal gun owner (and in any case a lot of the people on that subreddit didn't seem like regular establishment dems to me but I've not gone on reddit for years) isn't the same thing as going ahead with shooting trump though.
Plenty of Americans have incoherent politics and access to firearms.
That was what I was saying, it's probably someone with unconventional politics or someone motivated by something other than just political views, like someone with a serious mental illness.
