In terms of ACA, my problems with the "market reforms" is a matter of record - I think the regulatory reform/exchanges/mandate is bad policy. I preferred the expansion of public insurance (such as Medicaid expansion, which is the piece of ObamaCare that is unequivocally good and working. But we are where we are - ObamaCare is under fire and extremely unpopular. What do Dems do now?
The ACA is not changing any time soon imo. The President won't support any repeal and the GOP won't support any fixes. This means what to do next will necessarily be a 2016 issue.
Here's my modest proposal -- mend ACA as follows - replace the mandate with autoenrollment in Medicare for those persons who either do not qualify for Medicaid or do not have private insurance, using the existing tax credit/subsidy structure where applicable. Simple and effective imo. And politically feasible.
This would have the effect of providing insurance to as many as possible, improving the solvency of Medicare (improving the health of the Medicare pool will lower costs) and be politically popular.
My two cents.
