"I think that it is going to be part of the president’s job to deal with more than one thing at once."
Think about it. McCain wants to be president at a time when we're fighting two wars, with one on the way (Pakistan), a major financial crisis, an energy crisis and a global climate crisis. And he can't seem to handle multitasking.
Like I wrote earlier today: he simply can't do the gig. If ever there was a real life president who would decide to blow up the Moon on a whim, this would be the guy.
