There’s plenty of room to argue over who was primarily responsible for the implosion of the House Republican leadership’s Obamacare-partial-repeal bill last week. No less than fourteen lessons are drawn by my Washington Examiner colleague Byron York.

Many blame those purist members of the House Freedom Caucus who refused to accept anything less than a complete Obamacare repeal or, when one demand was met, suddenly made another. Many blame Speaker Paul Ryan and/or the Trump White House for insisting on bringing a complex bill forward in an unusually short period of time; it will be interesting to learn who insisted on such a tight schedule (the Democrats took 14 months to pass Obamacare in 2009-10). Many blame so-called moderate Republicans who moved to opposition in the closing days.
