A message to House Democrats: This is your moment of truth. You can do the right thing and pass the Senate health care bill. Or you can look for an easy way out, make excuses and fail the test of history.Tuesday's Republican victory in the Massachusetts special election means that Democrats can't send a modified health care bill back to the Senate. That's a shame because the bill that would have emerged from House-Senate negotiations would have been better than the bill the Senate has already passed. ① But the Senate bill is much, much better than nothing. And all that has to happen to make it law is for the House to pass the same bill, and send it to President Obama's desk. Right now, Nancy Pelosi, the speaker of the House, says that she doesn't have the votes to pass the Senate bill. But there is no good alternative.
Some are urging Democrats to scale back their proposals in the hope of gaining Republican support. But anyone who thinks that would work must have spent the past year living on another planet. The fact is that the Senate bill is a centrist document, which moderate Republicans should find entirely acceptable. In fact, it's very similar to the plan Mitt Romney introduced in Massachusetts just a few years ago. Yet it has faced lock-step opposition from the G. O. P. , which is determined to prevent Democrats from achieving any successes.② Why would this change now that Republicans think they're on a roll?
Alternatively, some call for breaking the health care plan into pieces so that the Senate can vote the popular pieces into law. But anyone who thinks that would work hasn't paid attention to the actual policy issues. Think of health care reform as being like a three-legged stool．You would, rightly, ridicule anyone who proposed saving money by leaving Off one or two of the legs. Well, those who propose doing only the popular pieces of health care reform deserve the same kind of ridicule.
Now what about the suggestion that Democrats use reconciliation to enact health reform? That's a real option, which may become necessary. But reconciliation, which is basically limited to matters of taxing and spending，probably can't be used to enact many important aspects of reform. ③ In fact, it's not even clear if it could be used to ban discrimination based on medical history.
