The Mississippi Senate on Tuesday rejected two proposals to expand Medicaid to people who work low-wage jobs that don’t provide private health insurance.

Both votes fell along party lines. Democrats who are in the minority in the Senate voted for both expansion proposals, and Republicans who are in the majority voted against them.

Sen. Chris McDaniel, a Republican from Ellisville, said Medicaid — a government health insurance program for the needy, aged, blind and disabled — has been “an economic nightmare” with rising costs for the federal government and state governments.
