I know what you mean, but they held a big rally with him there before the election and those there were followers, though not all USC students I am sure.
There are always some weasels on every campus, students and faculty. Embarrassingly, Susan Estrich is a law professor at USC, and I'm sure there are some other left-wing idiots. I didn't notice too many when I was going there, but that was about 20 years ago. Regardless, USC remains remarkably and impressively conservative, as much as you could expect on the West Coast.
