That depends on how that smartness is used. We've already had a president with a PhD in Woodrow Wilson. The most despotic president we ever had. We've now got an "intellectual" who has absolutely no clue how economics and the market place works.
What we really need is someone who trusts others to act on their own intellect. Someone who knows that being president does not mean that the oceans will recede. Someone who has just a common sense wisdom about them.
