Jonathan Chait's latest piece is well summarized by its title: "Sorry, Conservatives. Obamacare is Still Working." And it is. It's not working as well as some had predicted but it's working a whole lot better than the cocksure pronouncements that it would never work at all. More Americans have health insurance and they're paying less for it than they would have without the Affordable Care Act.
More significantly, there still is no viable Plan B, no proposal that would do a better job at keeping people covered. Donald Trump's is interesting. There are, of course, no details except that (a) every single American would be covered, (b) the government would pay for it, (c) it would be through private insurance companies and (d) he's such a great negotiator, he would find a way to make it all happen for less than we now spend. And he doesn't say this part but you can bet (e) it would be called Trumpcare.
