Why the heck is Sanjaya Malakar still on American Idol? (Actually, why the heck was he chosen as a contestant to begin with?) Maybe it's because Simon Cowell has sworn that he'd quit the show if the floppy-haired, hula-dancin' contestant won. Or maybe it's VoteForTheWorst.com, a site dedicated to, you guessed it, rallying people to vote for the worst American Idol contestant (or as they put it, the "entertaining contestants who the producers would hate to see win on American Idol"). In the past, they've "backed" John Stevens, Constantine Maroulis, Janay Castine, Scott Savol, Kevin Covais, Kellie Pickler, and Taylor Hicks -- their first real victory. Just how far will they carry their season six pick? Find out, on the next American Idol…
