Republicans have put themselves in a deep hole on ObamaCare, both politically and on the health-market merits, but maybe they’ll grab the rescue line now dangling in front of them. A potential compromise among the House’s contentious GOP factions could begin the climb out.

The chance to revive the failed repeal-and-replace bill developed this week when the House Freedom Caucus’s Mark Meadows and the centrist Tuesday Group’s Tom MacArthur struck a tentative deal. Their compromise would allow states to seek waivers to opt out of most of ObamaCare’s insurance mandates.

As House Republicans regain momentum in their quest to replace Obamacare, GOP moderates have done something unexpected: they’ve focused not broadly on covering the uninsured, but specifically on protecting those with pre-existing conditions. There’s a reason for that, and it has to do with wildly exaggerated claims that Democrats made when they were passing the law in 2009 and 2010.

The vast majority of Americans who are uninsured aren’t without coverage because of a health problem. They’re uninsured because of an economic problem: the problem that American health care costs too much, especially for lower-middle-income Americans who earn too much to qualify for government assistance.
