The party registration of tenure‐track faculty at 11 California universities, ranging from small, private, religiously affiliated institutions to large, public, elite schools, shows that the “one‐party campus” conjecture does not extend to all institutions or all departments. At one end of the scale, U.C. Berkeley has an adjusted Democrat:Republican ratio of almost 9:1, while Pepperdine University has a ratio of nearly 1:1. Academic field also makes a tremendous difference, with the humanities averaging a 10:1 D:R ratio and business schools averaging (...) 1.3:1, and with departments ranging from sociology (44:1) to management (1.5:1). Across all departments and institutions, the D:R ratio is 5:1, while in the “soft” liberal‐arts fields, the ratio is higher than 8:1. These findings are generally in line with comparable previous studies. (shrink)
