I think I'll be heavily down-voted for posting that on HN but in my opinion the reason most college graduates are liberal is that - whether we want to admit or not - colleges teach liberalism. I'm not saying that Big Brother is behind this, I think it "just happened" for many reasons.
As a consequence while most liberals think that they have the answer for life, the universe and everything and that they are objective, independent and "scientific" thinkers, they are more often than not just regurgitating packaged values that have been impressed on them.
You'll always see that 80% of the people are followers. The system teaches liberalism, so 80% of the people going through the system will be liberal just by following - often unconsciously. 10% of the remaining will choose to be liberal out of true critical thinking while the 10 remaining percents won't be. Those who haven't been through the system (drop outs, high school graduates, etc.) are more likely to have more diverse opinions. Which are then dismissed by flagging them as "opinions mostly held by uneducated people".
But what I've found is that education systems barely teach anything. For all the knowledge we've been presented, we just "really know" a ridiculous tiny fraction of it. This is why nowadays, you don't even need to be "smart" in the academical sense of the term to be in the top 5%, you just need to be a critical thinker in your field and think out of the box. Because it is indeed an extremely hard thing to do once you've been through college, as you've been nurturing the illusion that you learned most of the things you actually memorized. Many packaged values and referentials have thereby been patterned on your mind.
For all these reasons, it is in my opinion unlikely that most people won't feel liberal after going through college.
