Democrats are sharply divided between school "reformers" and so-called "traditionalists." They circulated competing manifestos during the presidential campaign: one side wants charter schools, merit pay and accountability for teachers; the other says don't blame teachers for failing schools, provide flexibility and better resources. Barack Obama has chosen an education secretary who has endorsed both sides. Will that mean gridlock or will Chicago's Arne Duncan finally overcome the "tired… debates" that have stalled real education reform? What about "No Child Left Behind?"
