“I’m not seeing how this new language, this proposed new language, does anything but make the bill worse, not better,” Diaz-Balart told HuffPost, adding: “Every time I read it, there are more red flags that keep popping up.”

HuffPost's Matt Fuller, who has been doing yeoman's work on a whip count, currently has 38 GOP members as either against the bill (17), leaning against it (10) or undecided (11). The GOP can only afford 22 defections.

And Diaz-Balart's comments are instructive. The MacArthur Amendment clearly moved the bill to the right in hopes of appealing to free-market conservatives, but it did nothing to address concerns about rising premiums for older Americans and the millions who the Congressional Budget Office say would be off their insurance under the AHCA. It actually created more problems for a moderate crowd that is concerned about having to answer for Obamacare's benefits being ripped from their constituents.
