I think we'll find this guy was not into politics. He spent his time doing psychopath stuff. Killing cats and dogs, Planning and fantasizing about killing sprees. If he did care about voting, he's most likely republican/libertarian. But my hunch is he didn't even bother to vote. I wouldn't think he'd be engaged in society in any way other than to make money or to find victims to prey on. I'd be cross checking this guy with missing persons for possible connections. I'd bet he's killed before.
