Every once in a while, liberal bloggers make a really good point. David Dayen, writing at FireDogLake, notices:

We keep hearing about how labor is so furious at anyone and everyone who voted against the Democratic health care bill that they plan to run kamikaze missions against them. The SEIU, for example, is forming a third party in North Carolina designed to dump three Democrats who voted against health care. Just to reiterate how much I think this accountability from labor is nothing but talk, consider this: [PA-12 congressional candidate Mark] Critz, saying in his ads that he opposed health care reform, has been endorsed by the Pennsylvania AFL-CIO.
