Nate Silver scores the summit:

Fundamentally, one's impression of where the health care debate stands is liable to be very similar to where it was 24 hours ago. Personally, I err a bit on the pessimistic side because (i) the math in the House, already challenging to the Democrats, has gotten even tougher with the death of John Murtha and the impending retirement of Neil Abercrombie; and (ii) it seems like there are a lot of ways the Democrats could fumble the exchange between the bipartisan tone they sought to strike today and their need to pass their policy in a reconciliation/majority-rules environment later on.
