Except he was playing to the tea party crowd claiming to be the tea party candidate and claiming to be a libertarian. (fyi, the Tea Party Express endorsed Scott Brown).
Geesh, I only heard the one (now-infamous) exchange between Brown and Kennedy at the most recent debate via YouTube and even from THAT exchange ALONE it’s clear the guy is definitely NOT a libertarian! No libertarian would EVER support Socialized Medicine! And if anyone tells you different they haven’t a CLUE what libertarianism means.
