You read that headline right. A leading Republican senator, John Cornyn of Texas, says the Ryan proposal for Medicare is exactly the same thing as the "Obamacare" program adopted for everyone else. He can't understand why more Democrats aren't on board. That suggests a variety of followup questions. Key difference: Republican Obamacare (that is, implementation of insurance exchanges and private subsidies in place of single payer insurance on older people) would reduce existing Medicare benefits. The real Obamacare increased medical coverage for everyone not in Medicare. Terrible in one case. Better than nothing in the other.
