Well, I'm rooting for a Fantasia/Diana tie. Since that's not very likely, I think I'm going to have to go with Diana. I actually feel that Tasia is a much more amazing talent right now. In fact, she's so talented that I think she's going to do great whether she wins or not. Diana, on the other hand, with her overtly young persona, may need the idol title to jumpstart things for her. So, I'm thinking that a Diana win is the scenerio that is most likely to have them both succeed.
And if Jasmine wants to succeed, she better hope that she's eliminated next. Otherwise, she almost certainly going to be JohnStevensified.
