At Cornell University, Republicans are an endangered species, according to a new report by Matt Lamb of The College Fix:

Eleven departments out of 19 surveyed show zero registered Republican professors: government, philosophy, anthropology, astronomy, dance, ecology and evolutionary biology, German studies, neurobiology and behavior, Latino studies, mathematics, and music.
A sum total of 17 Republican professors were found teaching within the College of Arts and Sciences, with the largest amount being five in economics and three in history.
Chemistry has two of 48 professors, comparative literature has one of 41, computer science shows two of 86. The rest were found in linguistics, molecular biology and physics.
