maybe this and the Olympics will suck up all the oxygen so that Obama will be able to vacation without losing a lot of ground. Also, maybe this will help him with women voters. He's already getting most of them, but maybe there are some holdout Hillary supporters (and even some Republican women) who will be reminded of McCain's adulterous history, esp. with Miss Buffalo Chip. Some may even remember their irritation at Bill Clinton for his pecadillos.
By comparison, Barack and his relationship with Michelle might be the thing that gets them in his corner. Whatever criticisms they may have, they can't deny the loving, respectful relationship they have and there is no hint of any scandal. And you know the Clintons and the Republicans have looked under every rock in Illinois trying to find anything resembling a bimbo eruption, not to mention Michelle would have cut his ass if he'd even tried it.
