Yeah, there are little pockets of us leftist hanging out in humanities departments, and social science or geography or environmentally-influenced disciplines--but even within these departments there is a conservative impulse.
To make it more clear though--think of the disciplines that command the most funding/grants.... business, engineering, hard sciences, medicine... these are dominated by conservatives and their politics rule universities (no matter how much fuss we crazy leftists cause ;)
Yahoo Report That Continues This Silly Controversy
Abby Normal supplies this extra report:
An alumni group dedicated to "exposing the most radical professors" at the University of California at Los Angeles is offering to pay students $100 to record classroom lectures of suspect faculty.
Which is ridiculous because they are professors--just go read what they write and you will have plenty of ammo ... and they call us "politically correct" paranoids?
