A couple thoughts on this. First, it's good that they're pushing back on Medicaid cuts. Because it means that all the pressure they're getting at the townhalls they decided to stop holding is working. Keep the pressure up. BUT...
...they all voted for the budget bill that included those $880B of cuts and they all KNEW that this implied massive cuts to Medicaid. They hoped people wouldn't do that math at the time, and figured they could avoid pissing off Trump and kick the can down to the road for the next vote.
IOW, they shouldn't be seen as principled defenders of Medicaid. They toed the party line, got heat at home and are now SAYING that they want to do this right. But watch their feet and ignore their lips. These are not people with a history of standing on principle, or for their constituents.
