What if Kerry had Clinton as VP. For two years, he wouldn't have to worry about having an "accident." Or, would he? Let's suppose he has an accident. The VP Clinton could serve for two years. What if he ascends to the highest office but names Hillary as president. She then names him as VP. She serves a certain amount of time, then she resigns and he can take over with less than two years remaining in the term. He then names her VP and she runs on her own as a sitting VP. Machiavellian? No, Clintonesque.
