I love the first one, but it does bare a great deal of resemblance to the McCain logo from a distance. I would absolutely hate for someone to think that there was any more support for McCain than there really is.
Although, I live in a pretty republican area... maybe it would be more fun for people to assume at first I was a McCain fan, only to discover the real message after closer inspection...
I'm not sure it's worth it. I may just stick with the "Don't blame me..." sticker.
