It's always a delight to watch liberals try to "diagnose" the causes of conservatism. Steny Hoyer believes that Tea Partiers come from unhappy families (a variant of the "nurture" argument). On the other hand -- in a "nature" argument minus the usual lefty proclamation of respect for "diversity" -- Colin Firth believes that conservatives are just biologically "different."
Apparently, it's simply impossible for people just to believe in limited government, political and religious liberty, free enterprise, military strength and traditional values.
Keep it up, guys. Liberals have no hope of winning the battle for hearts and minds if they can't even understand the reason so many Americans disagree with them and their agenda.
