Predicting the future of politics is near impossible.
Some unknown seems to lurk around a corner that throws all the predictions in disarray.

So much flies around Hillary that it is difficult to sort the true from the untrue (These seem true of most politicians in the public eye). It is very hard to say where she will be during the next election.
That being said, I'll make my prediction. Kerry and Gore will probably not run. Hillary will probably not be nominated. The person that will be nominated is probably someone who is currently out of the spotlight.
(If they would nominate Lieberman, I just might vote for him.)
