First things first: in addition to the big Scott Walker recall tonight, don’t forget that there are four more Wisconsin state senate recalls being decided. Democrats need to win only one of those to gain a majority in the senate. For national political spin all that’s going to matter is whether Walker wins, but for actual legislating within Wisconsin Democrats would have a clear victory with either result.

1. The Post has Wisconsin exit polls, and the key finding is this:

Early exit polling in the Wisconsin gubernatorial recall election suggests that union household comprise roughly a third of all voters, a share of the vote that is higher than either of the last two presidential or gubernatorial elections held in the state.

Voters in the recall also tilt positively toward public sector unions in general, but not by a huge margin. Voters split about evenly in their support for changes to state law that limited the collective bargaining ability of government unions, an issue at the heart of recall effort.

2. An Andrew Sullivan reader tallies up Politifact results by party. Many caveats apply — I have very mixed feelings about Politifcat overall — but the basic story is that Democrats had a smallish edge in the “true” and “mostly true” categories, while Republicans had a big, huge, whopping, and presumably embarrassing lead in “pants on fire.”

3. David Graham makes a good case that today’s big supposed Mitt Romney flip flop on the auto bailout wasn’t a flip flop at all.

4. Very interesting: Lisa Murkowski breaks with Mitt Romney and expresses support for the type of green energy loan program he’s been attacking.

5. E. J. Graff on why it really matters that Senate Republicans killed the Paycheck Fairness Act by filibuster today.

6. A fun piece on today’s other recall elections, from recall specialist Joshua Spivak.

7. Be ready for this: John McCain is going to be highlighting national security leaks to accuse Obama of compromising the country’s safety. A lot.

8. The continuing conservative freak-out over Mike Leavitt, pegged to head the Romney pre-transition team, over health care. Explained by Jonathan Chait.

9. Good Matt Yglesias post on debt.

10. The global progress of cap-and-trade, by Brad Plumer.

11. I suspect that this is going to be great.

12. Henry Farrell makes the case for funding political science.

13. And Jamelle Bouie on “extortion politics.”

What else?
