Above is a clip of Dave Weigel and David Frum discussing partisanship in DC and how neither of them fit very well in either camp at the moment. I'm beyond chuffed to note that both Dave and David have kindly agreed to guest-blog this next week while I take a short break. Underbloggers Patrick Appel and Chris Bodenner will be chipping in as usual. See you in a week's time. Be polite to our guests. They will be reading the in-tray while I waddle in some tidal pools.
