House Majority Leader Kevin McCarthy (R-CA) says forget about repeal and replace on Obamacare, just repeal will be fine. Once it's repealed you can look into replacing it. It's all clear. Republicans still have no plan or even any concept for how you replace Obamacare - at least if 'replace' is defined as something that will keep the tens of millions now insured insured. The immediate impact on millions of people will be huge. I'm curious whether they will be able to get this through the senate or indeed, in this form, through the House.
