If you look at political identification by academic discipline [1] you can see that the harder sciences tend to have smaller Democrat to Republican ratios relative to things like English Literature, Psychology, or Fine Arts.

To me, this implies there is an explanation other than partisan dislike for science that explains the large discrepancies in academic faculty. Whatever this reason is, perhaps it extends to other academic/scientific institutions.
