The debate over how to overhaul health care has widened a generational divide at AARP, the nation’s largest advocacy organization, reports The New York Times.

The group’s 40 million members are split about evenly between those who have access to Medicare and those between the ages of 50 and 64 who are too young to qualify for the federal health program. The younger group, as they age, face high premiums in the private insurance market, the newspaper reports.

AARP faces a delicate task in bridging the gap in its approach to the health-care overhaul. Organization leaders say they are focusing much of their work on strengthening Medicare but that they must also pay heed to younger members’ needs.
