Educated people don't vote Republican

Brad DeLong's Semi-Daily Journal: A Weblog: Jon Chait on the Political Composition of Academia: "But the rise of fashionable left-wing scholarship can be blamed for only a tiny part of the GOP's problem. The studies showing that academics prefer Democrats to Republicans also show that this preference holds in hard sciences as well as social sciences. Are we to believe that higher education has fallen prey to trendy multiculturalist engineering, or that physics departments everywhere suppress conservative quantum theorists?"
No direct link to Chait, unfortunately, but he's quoted extensively.
