Palin won't take the job. Haley would cost the GOP Ohio and Pennsylvania right off the bat. Martinez is a good choice but let's face it, the GOP won't go with two Hispanics on the ticket. Reynolds is a lieutenant governor. I agree that a governor in the second spot would add to the ticket and if you really want a woman then I'd suggest Fallin from Oklahoma. Otherwise Walker if he wins, Herbert in Utah, Deal in North Dakota, or even Kasich might be good choices. Brownback in Kansas would love to be in the running but he has to win first.
