To be honest I've got absolutely no idea as to who would be the best option to take on the role of President of the United States of America, as I'm not really clued up about American politics.  If you really wanted some opinions on the subject then you'd probably be better off posting the question on www.ebay.com, which is the American version of eBay, but even then you'd more than likely get a lot of conflicting responses as to whom the best option for the role of US President would be.
