The rise of the Tea Party and a rowdy 2016 Republican presidential primary has done little to boost conservative speech on the nation’s college campuses where right-leaning students say they feel intimidated and their views sneered at.

In a poll sponsored by Yale University’s William F. Buckley Jr. program, 800 national undergrads said that by a nearly two-to-one margin, colleges were more tolerant to liberals. Pollster Jim McLaughlin of McLaughlin & Associates, found that 37 percent felt school more tolerant of liberals views, just 20 percent of conservatives, and 36 percent equally tolerant.

And while students believed their schools do a good job to bolster intellectual diversity, half, or 49 percent, said they have “often felt intimidated to share beliefs other than their professors.” And 50 percent felt intimidated to share their thoughts with students whose views differ.
