Are we all left-tards here?

Come on now.  Are we?  While I myself wouldn't look for bible-thumping republicans, I think we should at least have a few moderates or radicals like libertarians ETC... 

Or is it the disproportionate european population here?

The problem with the US is that there isn't a socially liberal, economically conservative party.  If you want your vote to count, you either have to vote for an entitlement-crazed, union-controlled shit party or a party full of bible-thumping rednecks (with some corporations looking for handouts along for the ride).  It's unfortunate that libertarianism tends to attract tax scammers and conspiracy nuts.  The LP won't separate itself from them for the same reason old-style Republicans won't dump the Christo-fascists.
