    Perspective

    We could be headed for a new schism in the debate about health reform. Not the familiar gulf between advocates of the market and government, or the predictable one between deficit hawks and spenders, but a new one that crosses traditional partisan and ideological lines between advocates of long-term reform of the health care delivery system, and immediate help for the uninsured and insured struggling with health care costs.  This new rift is most likely to develop if tight money and a crowded agenda…
