Hey, she'll probably do it. It's the perfect opportunity for her to look like a good Democrat team player, while letting slip just enough "truth" to sink Kerry and clear her own path for 2008.
Actually, I've never understood this idea that somehow Hillary! must torpedo the Kerry campaign in order to run in 2008. It would seem advantageous to her as well that an 'idiot' dem. could win in '04. She would still be in charge behind the scenes, socialist agendas could better be advanced in a democrat administration. Favorable socialists could be appointed to courts, etc. all the while the public is getting more fed up with Kerry as President. THEN she could ride in as the Democrats' savior in 2008. There is no reason to suppose Kerry will automatically run for two terms if he wins this one.
