OK I'm backing Cook because a) if the Mr. and Mrs. Cook alliance is going to be broken up at least Mr. Cook should win and b) I think David Cook is the better artist

But I am very happy for one other reason. My real life name is David. In the 10 years or whatever of reality TV as we know it a David has never won a major reality show that I can think of.
Now that a David will win American Idol I can finally get that monkey off my back!
