I would ID as independent, though I'm a registered Republican because I want to vote in primaries and I was at one time a conservative (though I was unenrolled back then, ironically). My ideology could generally be called socialist, in particular I would call myself a Heterodox Marxist -with an internationalist leaning (and perhaps even a few communitarian features). There isn't a political party for someone like myself... I don't know what the Socialist Workers Party or whatever they're called are about precisely, though I'd likely join one such fringe party if this were a parliamentary democracy.
It wasn't a fucking essay question. There's no partial credit. Multiple choice, man. Just pick one.
Republican, by the way.
This from angus of all people!
