Let's hope so.
I still think Sen. Collins is likely to oppose the health care reform legislation that comes out of conference. But since the bill has gained momentum, and since it seems increasingly likely that passage won't require her support, the incentives have changed.
With no obvious way to prevent the bill from becoming law, Collins (and her corporate benefactors) may be more inclined to try to influence the final negotiations. And the only way to do that is by supporting the legislation--or at least pledging not to filibuster it.
