Of all the email I receive from elite university addresses, I’d say the email from MIT is the most conservative (Princeton and Cornell are close with Columbia and Penn following behind) while Harvard is the most liberal. I get very, very, little from Brown, and with one or two exceptions the stuff I get from U. Chicago is pretty mushy middle of the road. Most of the email is from grad students and academics, which may completely screw-up the sample. This is all extremely impressionistic. But I think it’s mildly interesting.
