Sarah Palin, Hillary Clinton, Jennifer Granholm, and Kathleen Sebelius are the most likely women to run for President, and actually have a chance.

Jennifer Granholm: Born in Canada
Hillary Clinton: The most likely to run and the most ambitous, but if Obama serves two terms, she will be an old hag in 2016. 2012 is her last shot, and it is against a President of her own party. not likely
Kathleen Sebelius: Old Hag in 2016, 2008 was her only shot but didn't run.
