I did a guest post today at Greg Sargent's Plum Line about the conservative closed feedback loop and how it supplied the real context for Sarah Palin's speech yesterday. Those interested in such things might want to click through to it.
Meanwhile, since I spent the day reading The Corner's coverage of Tucson, I missed my chance to be the first kid on the block to attack Mark Udall's idea that Members of Congress should sit all mixed in together for the State of the Union, not separated by party as they normally do. I think it's a terrible idea...well, to do it once as a stunt is only a bad idea, but overall it's awful. If you want the argument, the person who did get it first as far as I know is Dan Amira, and he nailed it, so I'll just send you there.
