The College Fix has researched political affiliations of faculty at UNC-Chapel Hill — and found that 16 departments have no Republicans. The report, by UNC-Chapel Hill student Alec Dent, surveyed 34 academic departments (most of the departments in the school) and discovered 615 Democrats and 50 Republicans or a ratio of 12 to 1. Dent wrote:

A closer look at the results shows that 21 Republicans, nearly half of the total, were clustered in the Global Business Center. Even there, Republican professors are outnumbered by the 41 Democratic professors. The department with the second highest number of Republican professors is the Romance Department, with four registered Republicans.

By the way, Dent found two registered Libertarians.
