Why have so many Conservative and Republican leaders...?

Don't forget, there's a lot of us "Joe the Plumber" conservatives that have switched over. I've been a registered Republican since 1968, and when McCain picked Palin, I said, "oh **** this", and decided to vote for Obama. At least Obama has enormous intellect, much more than McCain and Palin combined. I became very impressed with Obama after I heard him speak in some memoriable moments.
