No, he was one of the worst Presidents the US has seen! What he was brilliant at was getting away with lies, constantly.
It is obvious that you do not know many people with very high IQs. All the ones I know have no common sense, are terrible with dealing people and life in general! I would never intrust them to run anything!
BTW the person with the highest IQ I know is a truck driver barely able to cope with life, much less the responsiblility of raising a family, can only converse on one subject (though on that subject I would call him an extreme expert) and lives on the edge of starvation. These type of people are not who should run a country, they are usually non-functional in real life except in the one area that truely intrest them.
