I still see Dem politicians boasting about how many hearings, etc..., they had for Obamacare back in 2009. Sure there's a working the ref angle here - reporters shouldn't continue (they never should have begun) broadcasting Republican complaints (lies) about how the Dems didn't include them in the process - but Republicans don't care, Republican voters don't care, and most other voters don't care either.
Figure out how to beat this bill and/or cause maximum PR and electoral pain for anyone who votes for it. It isn't as if there hasn't been time to prepare for this. And, no, relying on "moderate Republicans" to do the right thing won't work.
