Yglesias declares victory:

The crux of the matter is that progressive efforts to expand the size of the welfare state are basically done. There are big items still on the progressive agenda. But they don’t really involve substantial new expenditures. Instead, you’re looking at carbon pricing, financial regulatory reform, and immigration reform as the medium-term agenda. Most broadly, questions about how to boost growth, how to deliver public services effectively, and about the appropriate balance of social investment between children and the elderly will take center stage. This will probably lead to some realigning of political coalitions.

Julian Sanchez isn't so sure.
