The National Review, a leading conservative magazine founded by conservative icon William F. Buckley, has a feature on their website called "The Corner", which is pretty much a combined blog for several of their contributors. It's a pretty good site for following up-to-minute conservative Republican thinking.
Pretty grim over there right now, at 1:39pm Eastern. An example.
UPDATE: 1:51pm. Now the National Review is turning on Sarah Palin! One article on their website says, re: Palin, "something's gotta change", and another says she is a candidate "Who Is Clearly Out Of Her League" and should quit the race.
