Fail phone to Nancy Pleosi and Harry Reid: if you don't have the votes to get your legislation reconciled, you have failed. The GOP will come after you in November if you pass the bill or not, at this point.
No proceedural matter can save you now. You lose. You have failed.
That's what it means when you don't win enough votes. Please ask the GOP from 2006 and 2008 what it feels like to not win enough votes. As a matter of fact, don't worry about it, you will learn soon enough.
