Now that we know that the Democrats lost Kennedy's seat in Massachusetts today, clearly because of discontent with the current health bill (since that was Brown's signature issue in this campaign), the interesting question is whether the Democratic Congress heard the message and will rethink the bill, or whether they are so committed to passage no matter what the public thinks that they will push ahead.
The smart thing to do would be to strip the bill down to the parts that have a broader, more bipartisan base of support, and settle for an incremental improvement rather than a wholesale liberal revolution. But Congress hasn't shown much tendency lately to do the smart things.
