Okay, so it's no surprise, but unless conservatives take a careful, concerted aim at the leftist monopoly of "public" education, the slide of Western culture into incompetence, irrationality and immorality will continue.
Here's the first few paragraphs from a very good report on this profound imbalance from the Young America's Foundation:
Using U.S. News & World Report’s ranking of the nation’s top 100 colleges and universities, Young America’s Foundation found that for every one speaker on the Right, there were roughly seven speakers on the Left. And while leftist speakers were awash with activists—including racial preference supporters, anti-war thumpers, and global warming pushers—those who fit into the “Right” category were not conservative activists but rather elected officials or presidential appointees.
The survey also uncovers separate graduation ceremonies at leading universities for lesbian, gay, bisexual, and transgendered (LGBT) students and reveals that prominent schools—including Yale, Harvard, University of Pennsylvania, Dartmouth, Northwestern, and Tulane—have a long history of shunning conservative policy makers on commencement day.
Notably, successful conservative media personalities including Sean Hannity, Rush Limbaugh, and Matt Drudge are absent from the list of graduation speakers despite The Fox News Channel’s ratings as the most watched cable news network, the dominance of talk radio, and the emergence of Internet journalism.

Conservative intellectuals including Thomas Sowell, Newt Gingrich, and Robert P. George were also passed up. Filling their places were the Charlie Rangels, the Oprah Winfreys, and the Bill Clintons.
Commenting on the study, Young America’s Foundation Spokesman Jason Mattera says, “For fourteen years, we’ve shown that college administrators are using commencement ceremonies to send their students off with one more predictable leftist lecture.”...
