In this year's health reform debate, congressional Democrats quickly took proposals for a single-payer system off the table, claiming it was "unrealistic."
But more than 9 million people in the U.S. have already signed on to a single-payer system that has proved both workable and popular: TRICARE, the Department of Defense's program for active-duty military and retirees.
Even more interesting: According to a Facing South analysis, nearly half of TRICARE beneficiaries live in the South -- states where congressional leadership has been most vocal in opposing public involvement in health care.
