U.S. House factions trying to revive legislation reforming health-care policy should consider not just changes in bill language but several changes in outlook as well.

First, they should stop thinking of this effort as “the” sole bill to “repeal and replace” Obamacare. Second, they should measure the bill not against all future policy hopes, but against existing law. Third, everybody involved – especially President Trump and House Speaker Paul Ryan – ought to trumpet and explain in easily understandable terms, a major new concession they would make to build political support for the bill.
