A local TV station had three people take this test to see how each one felt about the 20 issues included in the quiz. Then the web site matched them up with the candidate whose position most closely matched what they filled in.
Two of the three were very surprised at the match. One was at least in the same Party but the other one was not.
The third person matched up with her favorite candidate just fine.

I suppose I agree with her stances, although I dont support her) closely followed by Obama, who I support. The one suprise was McCain, whom I actually like a great deal, was towards the bottom of my list. That said, I like McCain because I agree with him on a few key issues that perhaps this test didn't cover, plus I mostly just prefer him over the other republican candidates.
