I think he'll do it. The GOP knows which ones voted against it. They have time to put together a plan to scare them into supporting it next time.
What plan? The whole point is that they couldn't scare them no matter what. They held meetings, they played good cop bad cop, they had Trump, Bannon, Kellyanne, Spicer, Pence, fucking everyone talk to these people, not one would budge.
I'm really curious to see what plan you think they'll cook up, because they couldn't come up with one at all the first time they tried this. The problem wasn't that they didn't know who was going to vote against it, the problem is that the people voting against it didn't fucking care about Trump or what he had to say.
