The topic of academic bias has been done to death in the blogosphere, nonetheless I was startled by this recent result. When it comes to the 2004 election, polled health sciences professors were 48.1% for Kerry, 51.9% for Bush, at least according to one poll. The social science professors were more than 87% for Kerry, and the physical and biological science professors were more than 77% for Kerry. Even business professors were more than 65% for Kerry.
Note that the linked article contains some interesting remarks by Larry Summers on the topic of academic bias.
