This has zero to do with Trump, and everything to do with the fact that the Rs ran on something they couldn't do.  I don't mean Trump, I mean the rank and file House and Senate members.  They were fine with symbolically voting to repeal O-Care, but now that they actually have to make it happen, they can't agree on what to actually do.  Now that there are consequences to their votes, they are realizing that just a repeal isn't going to happen, and that they need to work together to make it happen.
