Ah, 'higher' education...

Political groups listed in the survey included Communist, Libertarian, Green Party, Republican, NRA, ACLU, and Democrat. To confuse professors about the true aim of the survey, Yancey also included groups such as vegetarians and single parents.

Of all political affiliations, NRA membership was ranked as the most likely to hurt an aspiring professor’s chance of getting hired, with 41.2 percent conceding that it would “damage” an applicant’s chance of getting hired.

NRA members fared even worse than Republicans. Only 28.7 percent of professors indicated that Republican Party membership would damage a candidate's chance of being hired, according to Yancey’s research.

But the reason there aren't more conservatives/libertarians in higher ed is because they don't want to be there/aren't smart enough/don't care about education/etc.  Really, the leftists tell us so!
