I disagree with this completely. The GOP couldn't even get a simple majority to support a Senate ObamaCare "repeal/reform" bill after promising to deliver on that for years.
The only thing stopping the GOP from acting like a governing party is the bunch of GOP @ssholes who fill a lot of the seats in both houses of Congress.
Except it wasn’t a simple repeal/replace bill. It was anything but that, and that was because you couldn’t do repeal/replace under reconciliation. That’s why full repeal was never on the table. And the replacement was also constrained by reconciliation rules.
If McConnell had dropped the filibuster rule, they’d have been able to satisfy more members, and maybe even a Dem or two, and a bill would have passed, in my opinion.
