Medicare for all, or Obamacare for seniors? Or both?

Many have noted that the Medicare reform plan included in Paul Ryan's 2012 budget, though sketchy in detail, looked a lot like Obamacare for seniors plus a public option -- the public option being traditional Medicare, which would compete with private plans on an ACA-like exchange.  Throughout the presidential campaign, Ryan emphasized that his plan would not affect current seniors, only kicking in for those under 55 when the plan was enacted.

This year, to meet the GOP target of balancing the federal budget within ten years, Ryan is reportedly planning to move the migration age up.

That possibility has led Avik Roy, the most vocal spox for conservative health reform ideas, to stop worrying, love the ACA, and envision its fusion with Ryancare:

There has been an important development since last year’s House budget: the reelection of President Obama. Obama’s victory means that Obamacare will be implemented, warts and all, making it politically impossible to repeal, even if Republicans are fortunate enough to retake Washington in 2017.
