Also, a quick note: I'm over at Greg's place today, so blogging here might be erratic.
On to the good stuff:
1. Andrew Gelman has a note worth reading on where the biases are when (some) political scientists consider reform. I mostly don't agree with him (and I'll try to give a real response if I get a chance)...but it's well worth reading the other side, so I recommend it.
2. Sarah Kliff on where the doctors aren't.
3. Brendan Nyhan, on why we shouldn't pay too much attention to small demographic splits within horse race polls.
4. You may have seem something last week about GOP (possible) misbehavior in the Michigan legislature. Kevin Drum had the same reaction as I did -- sounds plausible, but what was this really all about? He looked into it, and tentatively concluded:
So in some sense this is similar to Republican abuse of the filibuster in the U.S. Senate. It's not outrageous in the sense that Republicans are doing something unprecedented and anti-democratic. It's outrageous in the sense that they're playing Calvinball: breaking a norm of governance by taking a tradition that was used occasionally in the past and turning it into a routine part of party politics.
5. And awesome campaign posters.
