What’s happening, presumably, is that modern movement conservatism attracts a certain personality type. If you identify with the downtrodden, even a little, you don’t belong. If you think ridicule is an appropriate response to other peoples’ woes, you fit right in.
Great quote from Krugman. Bush has made the GOP less conservative, less republican and more autocratic. Downright feudal. It is really interesting to compare how angry the left of center is at what the Bushies have done to how angry the right wing is at liberals for who they are.
