All he needs to do is pick General Colin Powell to be his VP. He would take away a boat load of the black and ethnic votes from Obama and crush him.
I'm no fan at all of McCains or the republicans but this move would just fuck obama in the ass.
Yeah, the black vote would just stampede to McCain after that.

On the flip side, Obama picking Kathleen Sebelius as his VP virtually guarantees the heaviest Democratic turnout ever. He may or may not win, but that should be his choice.
