Drug test? Give that man a fucking IQ test. There are plenty of great figures and thinkers throughout history that were high AF, but stupid powerful people lead to tragedy.
In fact, every official that ever runs anywhere for anything gets one, and if they don't break 100, they can fuck off. I'm not asking for genius, though that would be amazing. I just want to know that someone is capable of thinking for themselves before we give them any power. I feel that there would be significantly less puppetry going on in politics. Not to mention, I would really love to read about something that our president did without feeling internationally embarrassed.
