1. Philip Klein is right: Tea Party challengers don’t have to beat every incumbent; they just have to win once in a while.

2. While Sean Trende has an excellent analysis of the general election battle in Mississippi.

3. Stephen Saideman has a solid summary of the Bowe Bergdahl flap.

4. Seth Masket on messing with the other party’s nominations.

5. More on who doctors are giving to, from Sarah Kliff.

6. And Alyssa Rosenberg responds to Ross Douthat’s thoughts on masculinity.
