The way I look at it, the very thing he is using (unemployment) to get this healthcare passed is the very thing which is making his ratings dive and will be his undoing. The longer the vote is delayed, the less chance he has of passing it.
I'm sure he's impressing that fact on Dem congresscritters and Senators. The more the folks back home learn about his socialized medicine scheme the less support it will get and he knows it. If it isn't passed in some version before the break it may not pass at all.
But a less optimistic but more likely situation is that it will be passed in a version more acceptable to the general public that can be amended later when people aren't paying as much attention to include many or all of the same objectionable features of the original bill.
