I think Ryan could promise not to take up that bill and that would be a believable promise, namely because Ryan is very conservative and I assume doesn’t want to be seen as the creator of “skinny repeal.” But I’m not sure how enforceable this is. Ryan can do whatever he wants. Once the bill is passed in the Senate, if the House bill passes the exact version, that’s it. I do think Trump can play a role here, in telling Ryan not to take up this bill. Or doing the opposite.
