Here’s my answer: all it takes to be a good president is common sense.
There’s no such thing as good “governing” as distinct from any other sort of complex decision-making.
“Now, how does that record show any ability to run a country with a budget of trillions of dollars?”
If your standard for this “trillion dollar ability” is accurate, then there’s no reason to believe you have the experience merely to ask the question.
That is to say, working with larger or smaller numbers requires a only difference in mathematical calculation, not in the nature of practical application. A president simply has more people working under them than a corporate CEO.
(And of course, our goal is to decrease the former number.)
Let’s be honest. An individual with the amount of success in the private sector that Cain has, when combined with common sense conservatism, is very likely to be overqualified for the presidency. This is certain when you take into account current standards.
