Here's great insight into how Congress works. Health Care reform is a game of chicken. Some members arr pretending to be opposed to the bill so that they may be able to get goodies for their districts:
...if the representative wants to extract concessions from the Democratic leadership, it’s thus a good idea to signal uncertainty or even opposition to the bill — as many conservative Democrats have done.

Perhaps the health care bill has more support than is being reported
