Took the test twice and got Thomas Jefferson Libertarian.
"You are an idealistic, sometimes to a fault. You have faith in the goodness of your fellow man, and that core belief is at the root of most of your views. You do not, however, have faith in the goodness of Big Government. The bigger it becomes the less likely it is to rule fairly and justly. Bureaucratic corruption is a serious concern of yours, and steps need to be taken to restrict the rampant growth of the government. Ultimately, though, your idealism trumps your fears of a toxic and overbearing government. Humanity, after all, will assert itself and correct its leaders when they step out of line."
I'm not American though but that's what I got. I usually supported Jack Layton as a Canadian, I left the country before he died. Being in the UK now though I have no idea.
