Mitch Daniels is the only qualified candidate of the three you mention, even though he is the least charismatic of the three.
Chris Christie is great for New Jersey, but probably would not play well across the country. He doesn’t have much executive experience, and some of his activities with respect to his brother are questionable. Plus he is very seriously overweight.
Marc Rubio is from South Florida, which may in fact be even more corrupt than even New Jersey. He’s got a pretty face, and a nice story, and not much else, except a lot of questionable backers.
