I'd love to see Obama becoming president, but I could live very well with a president Clinton too.
On the republican side, I still don't understand why Guiliani failed so miserably. I thought he'd be the canditate with the best chances and also with the best ideas (from the republicans, that is).
Out of the remaining three, noone is a future president imo. McCain is just too old, Romney is far too conservative and I don't even want to start on Huckabee.
