The problem with looking for conservative intellectuals is that many of the people who espouse genuinely conservative ideals have long ago given up the fight. People like Goldberg, Krauthammer and Kristol have hijacked the conservative intellectual hemisphere with their brand of neoconservativism, which is actually far closer to both liberalism and fascism than Goldberg would like to admit. And in doing so, they completely intertwined themselves with the absolute worst sort of people, people like Pat Robertson, William Bennett or James Dobson who call themselves social conservatives because it sounds better than fear-mongering profiteer. To see someone like Bill Kristol so strongly championing someone like Sarah Palin is just fascinating in its implications. The only sane logic behind it is that he honestly believes that his party is either too stupid or too indifferent to demand serious or honest leaders. He thinks all they need is a gun and a cross and they'll fall in line. She is his Manchurian candidate, and she will drive him into oblivion.
The other conservative voices listed here are great. I like Andrew Sullivan, too, as eyebrow-raising as he can be. But if you are looking for intelligent, reasonable commentary from anyone who would still claim that the last eight years were in the right direction, you're dreaming.
