I actually spend most of my time around democrats, being somewhere to the left of party mainstream (though my gun-related activities also put me in contact with many right-wing folk, there's little else on which I and they have common points). A clear majority support magazine size restrictions. A lot would prefer to see all semi-autos and handguns banned, reasoning that bolt-actions are good enough for hunting, and pump shotguns are good enough for self-defense at home (and considering handguns to be dangerous enough to override their utility as a portable self-defense tool). And "just ban them all" is not limited to one or two weird guys, either.
I'll grant you that there's also a minority with a somewhat libertarian outlook on policies other than economics, but it's just that - a minority.
