President Trump has always been very vocal about his intelligence. On multiple occasions he has stated that he is "like a smart person" and that he has "one of the greatest memories of all time"! But just where exactly does Donald Trump rank among the living US Presidents in terms of intelligence? Although IQ tests and educational backgrounds are important in figuring out the mental acuity and sharpness of the Commander in Chief, there is perhaps no better barometer of intelligence than their performance in stewarding the country through tough economic and geopolitical challenges. Since this is obviously subjective, there is only one way to find out what this order really is! Rank this list in terms of how intelligent you think the six living current and former US Presidents are. (Although your ranking is your own, each ranking updates the average which everyone gets to see!)
