Sam. Everytime a contestant is eliminated, is creates additional swing voters for the remaining contestants. So that makes it unpredictable unless there's such a huge voting block for one contestant. For example, if there's consistantly about 30 million votes each week and over 15 million are always for one particular contestant. That's a significant indicator as to who will win. However I don't believe that's the case. Also some voters may stop voting if their favorite is eliminated. So there are too many variables to predict the winner accurately weeks in advance.
Kevin. I agree about Casey. While still IMO the most original musically, I think he's in danger of letting the hype about himself go to his head. He's no musical genius. So if he's thinking he can do anything and come off looking good, he may have had a wake up call this week.
