I won't try to psychoanalyze the "naysayers," as Mr. Orszag describes them. I'd just urge them to take a good hard look in the mirror. If they really want to align themselves with the hard-line conservatives, if they just want to kill health reform, so be it. But they shouldn't hide behind claims that they really, truly would support health care reform if only it were better designed.
For this is the moment of truth. The political environment is as favorable for reform as it's likely to get. The legislation on the table isn't perfect, but it's as good as anyone could reasonably have expected. History is about to be made -- and everyone has to decide which side they're on.
