HONESTLY, THAT’S A LOWBALL NUMBER I THINK:

Depending on the definition, maybe 3-5% of the US population is smart but seriously mentally unstable. That group heavily selects into politics, though. So maybe you're getting more like 10-15% among certain political types. That's enough to have a real influence on movements.
