Voters in Nebraska on Tuesday approved a ballot measure to expand Medicaid to 90,000 low-income people in the state.

State lawmakers next will need to work out a funding mechanism to pay for the state share of the costs of the expansion. The majority of funding for the expansion comes from the federal government, but the state will need to procure 7 percent of costs in 2019 and 10 percent in 2020 and beyond, adding up to millions of dollars in spending each year.
