No, it isn't that simple.
The Reconciliation Bill only deals with budget issues.
For comprehensive care to exist, it must be voted on a major Bill, not just a reconciliation Bill.
The fight will be over the Reconciliation Bill. If Pelosi/Reid can get the Reconciliation Bill passed first, then the passing of the original Senate bill becomes inevitable, as a practical matter.
No, the passing of the Senate version would not be inevitable.
The Reconciliation bill is not going to contain most of the provisions of the Senate version and that Bill would be defeated.
That's exactly the point. The Senate - because of the filibuster - was limited by Nelson, Lieberman and a couple others. But, because of the Budget Reconciliation process, they only need 50 votes (plus Biden).
Maybe the Senate or House Parliamentarian objects to some of the provisions in the Reconciliation Bill, maybe they don't. It's not an exact science, and the Parliamentarians do have some latitude in making their decisions. Also, rulings of Congressional Parliamentarians are not subject to judicial review, or so has been the tradition.
