They're about 2% of the population globally

@Fedor but the global population doesn't matter in this case, what matters are people who can be elected POTUS by 2063. The entire population has a 9% frequency; the currently-electable population, which excludes racial minorities to a significant extent, probably has a higher frequency, but that will definitely decrease by 2063 - almost certainly due to an increase in diversity, hopefully due to a decrease in White supremacy.

weird stat - most US presidents have been blue eyed

@shankypanky is that so weird given how it correlates with another trait that was shared by 89 out of 90 parents of Presidents?

@shankypanky but okay, two of them had gray eyes. That is really weird (plus three "blue-grays" and one "hazel-gray").
