I would be fascinated to know the IQ scores of all the US presidents, but I assume no such dataset exists. Being the president would seem to be a good example of a form of success in which IQ would not be that important relative to other personality attributes, like understanding what people want and how to (re)phrase it well, persistence, bravery, being able to spot strategic mistakes of opponents etc. It's not clear any of these attributes would be classically considered "intelligence" in the IQ sense, but they're all clearly valuable for politicians to have.
