Even though governors and lawmakers in five Deep South states oppose a plan to cover more people through Medicaid under the health care overhaul, 62 percent of the people in Alabama, Georgia, Louisiana, Mississippi and South Carolina support expanding the program, according to a new poll. The level of support for expanding Medicaid – the state and federal health insurance program for the poor and disabled – ranged from a low of 59 percent in Mississippi to a high of 65 percent in South Carolina, according to the poll by the Joint Center for Political and Economic Studies, a leading research and public policy think tank that focuses on African-Americans and other people of color.
