Unsurprisingly, Joe the Plumber is supporting McCain according to CNN's political ticker. Why should I care what he thinks about politics? I don't care who Oprah is voting for, and I don't care who Joe is voting for.
He does not speak for the "common man." Like most Americans, I pay my taxes in full and on time. I don't love seeing the money go away, but it is the only way to enjoy the way of life we are accustomed to in the United States. Apparently, Joe doesn't.
Also, I read an article about how he was unhappy with the media attention (only after that pesky lien was uncovered though). The best way to stay out of the public eye is to refrain from giving interviews to national news channels. So sorry Joe.
