It's Waaay Too Soon for Speculation, But............

Everything I read tells me that Hillary can't win the presidency, but my favorite betting site says she will. Another good seat for the play is Slate's Campaign Junkie 2008. I just wish I understood online betting; Intrade assures me that Democrats will take all in 2008, but can this really be true? Maybe if I were more of a gambler I would have more faith in the bettors, but I've read too many times that gambling doesn't pay.
I guess I should ask my Republican friend whose predictions are always 100% correct (and are based on betting sites) to give me another lesson. It's fun to read that the Democrats will win, even though it IS waaaaay to early!
