OK, I will jump in.
One the low end 95% of any US four year school will be liberal to very, very, very liberal. The only one that I know of that has any core common sense is Hillsdale College in Michigan and there is no hockey there yet.
One way to gauge the campus atmosphere is to look at the curriculum for majors and the elective courses. Some of these colleges will never leave the 60s and the modern re-incarnations at other schools are comprehensive. Courses can range from weird to completely disgraceful. Tacking on to this topic are the post-election polls of how campus faculties voted and where they gave their money for candidates. Those news stories are very available in the public domain.
If there is parental concern about politics on campus it is very unlikely it will affect the hockey experience. The affects will be felt in the classroom.
