A lot of it has to do with the nature of the graduate school system, which winnows out conservatives by topic (i.e., you can’t write about military history, or biography) and forces students into writing “social” or “ethnic” history in order to get a degree. Likewise, once in power in the university faculties, they only hire like-minded people.
