Hmmm... Is this such a bad thing? Maybe, rather than replacing Obamacare with Obamacare Lite, just sit back, do something important (taxes? immigration?? infrastructure???) and let Obamacare collapse. Then you can do it right.
Well, maybe not. You seem to be Pug-ugly Lite lately!
Let it collapse.
Move the subsidized folks to Medicaid.
Open the whole thing to the free market and back the Federal government out.
