LINCOLN, Neb. — Advocates who want to expand Medicaid in Nebraska under the federal health care law are launching a petition drive to place the issue on the November general election ballot.

A new campaign dubbed “Insure the Good Life” will formally announce the petition drive Friday at the Capitol.

If it passes, Nebraska would join 32 other states that have expanded coverage as part of the Affordable Care Act. Nebraska lawmakers have rejected five previous attempts to do so through legislation, and a proposed constitutional amendment introduced this year is stuck in committee.

Expanding Medicaid would provide coverage to an estimated 90,000 low-income adults between the ages of 19 and 64 who have no dependents. Gov. Pete Ricketts opposes expansion efforts, saying it would draw resources away from other vulnerable groups.
