Ed Kilgore argues that President Obama should take only part of the blame if Obamacare fails, since the Supreme Court and Republican-run states undermined it. The Court made it easier for states to decline to expand Medicaid, and many states took advantage of their increased power. Many states also, as Kilgore complains, “did not bother to create their own exchanges or undertake the kind of public-education measures that might have encouraged broader enrollment.”

It seems to me, though, that if your plan strikes seven justices—including one of your own appointees—as unconstitutional, that’s a flaw in your design. Ditto if your plan requires the active support of people who hate it, and over whose objections you rammed it through.
