Maybe you.  After all, this is America, where any kid can grow up to be president.

Seriously, though, I think a lot of votes for Bush in the last election were mostly votes against Kerry.  The intervening years of frustrating war, troublesome economy and general displeasure with the current administration are likely to push the pendulum back to the Dem's side.  This fall's congressional election will probably demonstrate this trend.  So long as the Democrats ignore their rabid left and choose a centrist candidate who isn't absolutely disgusting, that'll be the one that gets elected.
