Over at Grasping Reality: Jon Gruber in 2011: Yes, Subsidies Are Available to People Purchasing Health Insurance on the Federal Exchange

The truly remarkable thing about Halbig/King is that conservatives care much more than liberals do that the health exchanges actually work. Health exchanges are a last-ditch conservative attempt to keep private health-insurance markets from collapsing under the weight of increasing adverse selection and decreasing willingness to provide a large tax subsidy for employer-sponsored insurance. If the exchanges fail, the liberals try again in another decade with single-payer–Medicare for all–in order to attain near-universal coverage. If the exchanges fail, conservatives are out of arrows.

I have never understood why conservatives interested in health policy have not drawn a line in the sand here–have not said to their political masters: “Yes, we know that you have a strong partisan interest in destroying the signature accomplishment of a Black Democratic president. But the substantive policy stakes are too high.”
