What's dragging the Democrats down in the health-care debate isn't confusion about details. On this the president and his supporters have proven themselves the ablest of technocrats, easily identifying each plan's particulars and its shortcomings, laying everything out on nice flow charts. It is the big questions that are tripping them up. Concerns about the size and role of government are what seem to leave reformers stammering and speechless in town-hall meetings. The right wants to have a debate over fundamental principles; elected Democrats seem incapable of giving it to them.
