Presidential candidates should be entire teams early. I don't believe that any of these candidates are solely competent in all the areas a president has to know. The candidates should have a known economy guy, military guy, social issues guy, etc. (and (or gal!) after each one), that are vetted nearly as much as the main candidate and who get out and speak to their thing. I'd be fine with a president who doesn't even know that much about any one thing if he has a dream team of people who'd whip ass at their thing.
