smart people can be wrong about some things...and still be smart
i know a smart person when i see one - i assess how he thinks acts and talks. his social position and formal education count...but they're secondary. i don't have to agree with his politics, his religion, his ethics to judge him.
maybe you have different standards
I never argued about whether people differ in IQ and education. I simply don't want to be governed by people chosen on these factors. If smart people with other qualities manage to get elected, that's OK.
