Happy Birthday to Barbara Babcock, 77. Excellent work on "Star Trek" and in her nice "Cheers" episode; I mainly think of her as from "Hill Street Blues."

Right to the good stuff:

1. Ed Kilgore sees little rationale remaining for Chris Christie’s presidential campaign. Could be, and Kilgore makes good points, but it’s still early.

2. Philip Klein critiques the Dave Camp tax reform proposal, calling it a solid step toward reform.

3. See also Jared Bernstein’s criticism that the bill doesn’t achieve long-term revenue neutrality. That’s important if correct, but I disagree with him about revenue-producing tax reform. I don’t think it’s possible, and if Democrats want tax reform they should give up demands to generate revenue from it.

4. While Stan Collender thinks the proposal kills off tax reform for a while. I don’t really see that; if Republicans won’t accept any tax reform that increases taxes (while being overall revenue neutral), then there was no hope for any bill in the first place.

5. Michael Brendan Dougherty gets ready for CPAC by thinking about the problems of movement conservatives and the Republican Party.

6. Hans Noel on activism and polarized parties.

7. Where are elections most problematic? Pippa Norris, Richard W. Frank, and Ferran Martinez I Coma present world rankings of electoral integrity.

8. While Jennifer Victor explains how political scientists learned how to play real-life politics.

And Nick Baumann has a look back at some pundits who went off the deep end in November over the botched ACA rollout. Very good.
