Here is another one of those "match yourself with the correct presidential candidate" Websites: Glassbooth
It's one of the better ones I've seen. Glassbooth first asks you to select the issues of importance to you by rank and then offers you specific questions on those issues.
I tried it twice over two consecutive days.
Yesterday, it matched me with Ron Paul at 80 percent and John McCain at 74 percent. Today, my match with Congressman Paul decreased one point to 79 percent and my affinity with Senator McCain dropped to 68 percent.
(My rankings of the issues must have changed somewhat between the two tries.)
