Is Kerry really running for VP?

Kerry's relentless attacks on Dean coupled with his vanishing poll numbers and his self-financed campaign (home mortgage) make it sound to some like he's really running for VP under Clark.  Kerry does the dirty work, Clark stays above the fray, Clark gets the nomination and taps Kerry as running mate, and Kerry For President somehow gets folded into Clark/Kerry 2004 in a way that pays off Kerry's campaign debt.  Kerry is going to keep chewing Dean's ass in state after state no matter what his own poll numbers do, because it's Clark's numbers that he's actually trying to prop up.

Does this make sense to anyone else?  Am I missing something?
