House Minority Leader John A. Boehner (R-Ohio) wasted little time blasting the White House, saying that the president "crippled the credibility of this week's summit" by working off the Democrats' bills. But when Obama invited congressional leaders from both parties to offer their best ideas, he never promised to abandon the principles behind the reform effort. As the president has said several times, the administration is committed to extending insurance coverage significantly, improving the quality of care and controlling costs. A few Senate Republicans have embraced those principles. But party leaders seem content simply to slow the increase in cost. The leading GOP proposal to expand coverage and improve efficiency is half-hearted at best.
