Well, no, cancel that; I am somewhat surprised that I supposedly "side with" Mitt Romney on as many issues as I do, and I am likewise somewhat surprised I "side with" the Republicans more than the Libertarians, but that could be because the Libertarians are increasingly less small-l libertarian every year (though it is not exactly like the Republicans are libertarian, constitutional, or much of anything in common with me, so I have some reservations).
The 2% siding with the Democrats, the 17% siding with Our Glorious President, and the "no major issues" in common between me and him? Yeah, shocking, I know.
Anywise, you can take the test here, and my comprehensive results are apparently available here. For most of the questions, if you hit the "Choose another stance" option, you will probably find an answer that will give you a more-accurate result later down the line.
