Larger population means larger representation. If you say the Netherlands only has about 100,000 idiots, that's roughly half a percent of their population.
Half of a percent of the US population is over 1.5 million. And I promise you, we have a waaaaaaay higher percentage of idiots than that.
Maybe if he forgets half the shit he's said that directly contradicts the other half, and doesn't try to nuke a hurricane over Mexico.
