Via Matt Steinglass, John Sides applies some simple game theory to the health care muddle:

[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. This raises the possibility, as one friend noted to me, that the prevalence of these signals in news stories may inflate the perceived chance that health care reform will fail in the House.

Along these lines, Stupak is sounding more optimistic.
