Hillarycare ended up a political failure and set back the cause of health care reform for nearly two decades. It’s not an episode that Hillary Clinton would want discussed during a 2016 presidential campaign. If Obamacare thrives, there will be no reason to look back to Hillarycare and drag these charts out of the dustbin of history. But should the Affordable Care Act falter or collapse, a question will loom: What would Hillary do about health care? Her past record would be raked over and that would likely not boost her presidential prospects. Having screwed up in the early 1990s, could she argue that she would do a better job in reforming the health care system than Obama?

It would be best for a Clinton 2016 campaign for health care to be off the table—with no need to revisit all this inconvenient ancient history. That means she and Bill should be hoping that the implementation of Obamacare proceeds well—and they should do all they can to encourage that. So Bill Clinton ought to coordinate (closely) with the White House on what stuff he should be explaining. It’s not only the president’s political fortunes that are tied to Obamacare.
