I can't stand Santorum. The guy is rude (seriously, he'll either interrupt you mid-sentence or just won't shut up in order to get the last word), has anger issues, and focuses way too much attention on social issues instead of the real political issues at hand. I was glad to see him get a beatdown from Romney especially with the Arlen Specter criticism because it exposed Rick as a one trick pony. When push comes to shove, all he has to go on is ROMNEYCARE = OBAMACARE. After hearing that for the past dozen debates, I was sick and tired of hearing that and thankfully so was the audience who booed him for bringing it up again.
The fact that even Ron Paul kicked Rick while he was down made it even better!
