Data on political polarization in America is really interesting. One feature of the data I find fascinating is that in 1994 many people were not "consistently liberal" because they opposed gay marriage. With the big shift toward acceptance of gay marriage these people are now considered "consistently liberal" and by Pew's reckoning this means that liberals have become "more polarized". In my opinion there is no morally defensible compromise position on whether homosexuals deserve their natural rights, so I find this quirk of the survey interesting.
If you look at the ten questions of the Pew survey, it seems to me that anyone who can answer on the conservative side of all ten questions (in order to earn the "consistently conservative" epithet) must be the biggest jerk on Earth, whereas someone who answers on the liberal side of all ten has sensible and morally justifiable views, hence I take all the hand-wringing over polarization with a grain of salt.
