Liberals always knife each other in the back eventually.

My guess is this isn't liberals turning on each other, but conservative professors finally speaking up. Econ tends to be the only social science department with a fair percentage of conservatives (not surprisingly, since if one studies the subject seriously, one realizes that the left's ideas on it are at best hopelessly naive, at worst a deliberate snow-job perpetrated as a power-grab).
