What do the Blue Dogs Want?

Paul Krugman in the NY Times

Krugman starts off like this:

To grasp the problem, you need to understand the outline of the proposed reform (all of the Democratic plans on the table agree on the essentials.)

I'm glad to hear this, he must know more than the experts on the Bill Moyer's Show did. But he goes on:

Now, however, they face their moment of truth. For they can’t extract major concessions on the shape of health care reform without dooming the whole project: knock away any of the four main pillars of reform, and the whole thing will collapse — and probably take the Obama presidency down with it.

Is that what the Blue Dogs really want to see happen? We’ll soon find out.
