"indoctrinate" students to a liberal agenda by encouraging higher college enrollment. He allowed Santorum to go on and on about how going to college as opposed to a trade school shouldn't be the only way for someone to get ahead in life without every pinning him down on how going to college is supposed to be "indoctrinating" anyone.

Here's more from The Hill on Santorum's appearance this Sunday -- Santorum defends college 'snob' remark:

Republican president candidate Rick Santorum defended his statement Saturday that President Obama was a "snob" because he has said he wants everyone American to have the ability to go college.

Appearing on NBC's "Meet the Press" on Sunday, Santorum said he does not believe that going to college is the only way for Americans to become successful.

"What I've said is I want everyone to have the opportunity to go to college, or whatever other higher training skills," he said. "But it doesn't mean you have to go to a four-year college degree….I think everyone should have the opportunity. It's about what's best for you." In a speech to the conservative Americans for Prosperity group in Michigan Saturday, Santorum said Obama's views on higher education made him "snob."

"President Obama once said he wants everybody in America to go to college. What a snob," Santorum said during his AFP speech. "There are good, decent men and women who go out and work hard everyday and put their skills to test who aren't taught by some liberal college professor that tried to indoctrinate them.

"I understand why [Obama] wants you to go to college," Santorum continued. "He wants to remake you in his image."

Or maybe he understands that college graduates earn significantly more than non-college graduates. However, Santorum is also selectively ignoring the fact that the Obama administration has made a commitment to invest in vocational schools and community colleges as well.
