1. John Sides has the definitive "what can presidential speeches do" post. Excellent. Also fun: Steve Benen on Westen.
2. Economy and budget: Mark Thoma on uncertainty and regulation; more on that topic from Matt Yglesias; Stan Collender explains baselines; Yglesias on currency wars; and Collender on what happens to budget deals as they age.
3. Electoral politics? Josh Putnam as always has the scoop on the GOP calendar of primaries and caucuses. Also Rick Hasen explains astrotweeting, Alan Abramowitz on electoral college bias, and voteview has ideological estimates for the Republican presidential candidates.
4. John Yoo, still wrong. From Conor Friedersdorf.
5. Facts and fact-checking, from Greg Marx; Adam Serwer explains what happens to people who rely on watch Fox News. And Paul Waldman on how Glenn Beck shows the agenda-setting power of the cable nets.
6. Governing stuff: David Frum on unsung heroes; Alex Pareene on whining rich people. Tim Fernholz believes business could learn something from government.
7. I'm still really enjoying Eric Loomis's series of state-by-state politicians: here, Vermont.
8. And a plea for the four-man rotation.
