If the Republicans know what is best for themselves, they will unanimously vote NAY
I basically agree with the edited although for different reasons, the current structure is set up in such a way that I see very little benefit for the Republicans to cooperate on the final bill. If all they care about is winning elections, they should insert their ideas everywhere, pretending to go along with it, and then unanimously demonize it while attempting to convince the public that it's the worst thing since the Holocaust (if not worse) and the most partisan thing since the word partisan was invented by the partisan parties of partay.
And then the Democrats can continue do the same thing and scare the public whenever the Republicans try and reform something.
It's easier to scare semi-apathetic swing voters than it is to convince your base that the other side may have a few good ideas thrown in there.
