They have a plan that throws 1 million people out of their plans and raises the deficit.
It will increase the deficit by $74B over 10 years, and reduce the incidence of employer-provided healthcare plans for 1M people, who the CBO assumes will go onto Medicaid. Clutching at straws.
If it hadn't been just a few weeks since Republicans trumpeted a CBO report showing that Obamacare was going to throw 2 million people out of work, I'd feel more sympathetic to that argument... but I think they've been hoist on their own petard.
