I agree with most of you guys.
If Bush's popularity keeps going up, Republican party will win no matter who runs on the Dem. side in 2008. If this is the case, Hitlery will not run when she know that she would lose.
2008 is her chance: by that time she has gathered more support (not because she's good, but because of her hubby).
I don't think that she runs in 2012 because her hubby's influence (read: favors he did as Prez to other Representatives and Senators) would be less, because of the ever-changing Senate and House seats; therefore, less support, unless suddenly she does something that her party thinks she deserves so.
Of course, if other Dem. candidates emerge and overtake her, then all bets are off, and her dream as a First Female Pres in US goes bye bye.
Now, as far as Republican candidate is concerned (assuming Bush wins 2004), the war vs. terrorists go as plan, economy is improving(
it improves somewhat now), then Republican party will win again in 2012. Of course, whoever runs 2012 will have the support of Bush.
