After the American Health Care Act went down in flames last month, blame fell mostly on the House Freedom Caucus, a cabal of conservative anti-establishment Republicans. But if the revised version of the Obamacare overhaul similarly fails, no honest analyst will be able to blame conservatives. Blame will belong wholly to centrist Republicans.

In every election campaign since 2010, every Republican has pledged to repeal Obamacare. Since Republicans rode that promise to a House majority that year, the House has voted more than 90 times for repeal (symbolic votes, all, under President Barack Obama). Now the Freedom Caucus has announced its support for an amended repeal bill, Republicans are closer than ever to finally delivering on their promise. It relies only on centrists to rejoin their party on this crucial issue for which the voters put them in office.
