At healthinsurance.org, I explore a possible future political deal to amend the ACA, with help from Jack Hoadley of Georgetown and Harold Pollack of the University of Chicago:
One might assume that Republicans would never go for a Medicare buy-in, as it would expand the ranks of those who get "government-run" insurance. But what if the buy-in were limited to Medicare Advantage plans, the GOP's beloved Medicare stepchild?
Republicans might view a buy-in limited to Medicare Advantage as a gateway drug. At present, only 2% of Medicare Advantage enrollees switch to traditional Medicare, so those who came in via a buy-in would probably stay in. Increasing MA's already-growing market share from the current 30% toward or beyond parity with traditional Medicare might be tempting to GOP lawmakers.
