If this bill turns out to have huge negative consequences (and I think it will, but that is for a different discussion), the public pressure will be squarely on repealing it, not strengthening it.

We have seen this movie a thousand times.  Republicans will claim "too much government is the problem", Democrats will offer up some pathetic succotash of a few graphs and dry analyses of market trends and "Don't blame us" weaselry, etc., and the public will (as always) be distracted and brainwashed into shouting for Conservative bumper sticker "fixes."

You are still relying on the Democrats in the future to listen to public pressure to make this bill better?

1.  They are unlikely to have the Congressional votes in the foreseeable future that they have now

2.  Most of them aren't listening to their constituents, who currently support a public option that isn't being fought for

3.  They will be saddled with ownership of this bill, which will reduce their credibility to be trusted on crafting the next one

4.  They are terrible politicians, terrible salesmen and terrible negotiators, especially on a major issue like this

and 5.  The problem will be more entrenched and more expensive the next time they work up the guts to try to tackle it (if ever again in our lifetimes)

Never underestimate the growing ignorance of our citizenry.
