Happy Birthday to Cloris Leachman, 86. Weird that imdb got her "known for" horribly wrong; I assume the correct answer is Mary/Young Frankenstein/Last Picture Show/her current sitcom, no?
On to the good stuff:
1. Absolute must-read of the day: Jonathan Chait, explaining not only Paul Ryan but also Paul Ryan worship.
2. Nice piece about health care reform implementation by Sarah Kliff, who looks at the Massachusetts example.
3. Seth Masket on the Edwards/Clinton question. I'll stand by what I've written, but at this point I'm mostly voting "overdetermined" on this one.
4. And Nate Silver's definition of swing states is the right one. At least, those are the states to pay attention to. If you're going to pay attention to states. Which you shouldn't this early.
