No no no, you gotta go to the Home Depot to get the real pulse of the day-labour bloc.
You can walk outta there with a three-pack of bulbs and they'll STILL ask you if you need help.
That's hard-core, I say.
However, I think that the difficulty with the American political system is less about the smarts of the people running for office.
It's more about the ethics and the sanity.
You have to be insane, literally have something wrong with you, to desire that much power. And... to actually climb the ladder so high, to give up all the vestiges of a normal life or any kind of principles to get up to that tier before the highest heights, you pretty much have to be amoral to the precipice of sociopathy.
People who are just crazy don't have the focus run for office, they're generally just homeless or religious figures.
People who are just sociopathically amoral generally don't go through all the trouble of politics when there's so many normal people to rape, torture, kill, humiliate, manipulate, etc. You can easily just become, like, a sports coach or a cop or some far pettier form of bureaucrat than president or senator to mete out enough cruelty for a lifetime.
To really wanna lead a country AND have the focus and intellect to pull it off...
You really have to be a perfect storm of madness and ethical numbness... along with at-least above average intellect and a path of access to vast amounts of money. Without any one of those traits, you're gonna fail.
Without money, no one will be able to hear you. Without above average intellect, you'll trip over your dick way early on. Without ethical numbness, you wouldn't be able to sleep at night making the choices you have to make to get up to the big stage. Without madness, you wouldn't feel the need to go so very very far to get your fucked-up power jollies.
An IQ in at-least-the-low-hundreds is the least of those traits because enough money can paper over those kinds of mistakes, really.
