I don't think anyone understands all of it. There's just too much of it. If it was as good as it was supposed to be, Democrats should have had no problem using it in their campaigns (the same is true of financial reform).

Add to that the fact that pieces of it kick in slowly over the next 4 years - so it's not like you can point to "cause and effect" now for those aspects of it and you have a law that is still more of a question mark than anything else. One thing that people ARE clear on is that the 'public option' didn't make it. So you'll have people who wanted that being disappointed (since they tend to believe that was what was needed for TRUE reform) and the people who DON'T want it are unhappy becuase of what WAS in the bill and the THREAT that a 'fix' *will* include it.
