What's comical is your insistence that an idiot could become president of the United States. That's even more farfetched than claiming that an idiot could become vice chancellor of Austria.
Lol, yes, an idiot can become president of the United States because we have Trump case in point. If there was a test, that tested the intelligence level of the President you may have a point instead of an election that test the popularity of the President. History have put idiots in position of power because they are easily manipulated so what make you believe that you have to actually be intelligent to become president. I know a lot of people voted for Trump because he is a billionaire as if that was the measure of his intelligence.
