I don't think being a Fortune 50 CEO is necessarily the best preparation for president, but there is definitely a lot of overlapping skills. This is very different than the businessman as politician fetish the country often has; running a small/family business doesn't require the same skillset.
I'm talking about the voters. You can't fire the chunk of voters that didn't vote for you.
I guarantee a lot of blue states would like to fire the red states who consume their tax money disproportionately.
However, we don't allow that because we are the United States of America and not the United States of People Who Agree With You.
