I would be shocked if they didn't raise the ceiling. Republicans are just putting on some good Ole political theater. They don't want the market to crash either
I wouldn't necessarily be so sure about that. In their minds, they don't really have an obligation to help Democrats out since they can raise the debt ceiling via reconciliation, but just don't want to do so. It's essentially what they've been since July now.
They will either have to do it on their own or go to Republicans asking what concessions can be made that will make you say yes.
