Any member of Congress who ran in 2014 pledging to vote for the repeal of the Affordable Care Act (ACA, or Obamacare) should of course do so. That was a campaign pledge. But having done that, and seen it lead to nothing, opponents of the ACA need to move on to a more productive and realistic strategy to achieve the core elements of a more conservative vision of health care reform. That approach could well meet with a measure of bipartisan support, given the enormous practical challenges facing the ACA.
