Brian,
Your last 3 paragraphs are right on, but I would have substituted "liberals" for "conservatives" in the 3rd last paragraph. The republican majority will be nothing like the bogeyman that liberals make out conservatives to be. And I agree with you that conservatives, as liberals portray them, would not be able put together a governing coalition. But those conservatives are not the defining force in this administration.
Why is the NYTimes magazine "shocked" to find out that 'conservative' Pete Domenici can support more funding for mental health care? Whydoes Ann Coulter keep hitting that raw nerve when she gives examples of liberals who "hate" conservatives? Could it be that Ann Coulter is Nothing like what liberals believe conservatives should be?
There is a Boston Globe column (sorry I don't have the link) by a univ prof, self described man of the left, who analyzes why the left is having so much trouble on the Iraq war. Either they are antiwar for its own sake (moral high ground) and then cannot admit the benefits of the war in Afghanistan, or they are moving off the intellectual reservation and actually supporting military action. When the left cannot no longer has the moral high ground and still rejects realpolitik, there is nothing there. The left won't be recognizable in a few years either.
I go back to Bush's nomination speech where he said that his adversaries had never faced anyone like him. I think that is true, and many liberals are just pining for the good old days when conservatives would shoot themselves in the foot, or just be people that could be easily despised, like a Jesse Helms.
Maybe liberals are just fighting the battles of the last election cycle.
