I have a question: If a vote is held and midway through it becomes clear it won't pass, is it possible for Ryan to suspend voting and continue negotiating with the people he thought would be on his side, or does the bill have to fail before they can renegotiate it?
He could negotiate with them on other things while holding the vote open. But I don't think he can cancel the vote when it's in progress. He'd have to let it go at least 15 minutes but as soon as the vote closes, that's the final count.
