The political affiliation of these individuals was therefore not accessible. In other cases there was more than one individual with the same name, again making a positive identification impossible

This implies that they searched voter records and if they found one and only one listing that matched the name of the professor, then they counted him/her as positively identified. Pretty dumb.

Regardless of the flaw, I'm sure that there is a discrepency between liberals vs. conservatives teaching humanities. Heck there's a big discrepency between libs vs cons in the teaching profession, at all. So get with the program, all you cons: let's have some programs to attract you all to teaching, if it's something you are so concerned about.
