You aren't voting for who is the most talented then. All you are voting for is who sang a song you liked which is not the point of the contest. You can certainly pick whomever you want and for whatever reason but don't try and say that Kevin is still here because of his talent or fan loyalty. I firmly believe that people are voting for him as a screw you to American Idol.
I vote for who I would actually buy a cd of. Between Kevin and Elliot, I would buy Kevin's. I like the songs he's done.
