Conservatives in the academy

David Brooks writes in the Wall Street Journal about conservatives not being welcome in academia. Juan at the Volokh Conspiracy agrees, and links to several other posts on the topic.

American intellectual life is recreating the division between the Red
States and the Blue States made famous in the Bush-Gore election of
2000. Liberals are over-represented on most university faculties,
and conservatives are over-represented in well-funded, well-connected
think tanks. We seem to be self-segregating ourselves politically
the same way many cities self-segregate by race. It’s sad to see
how quickly America is becoming two countries.
