TRENTON, N.J. (AP) — As states look to trim billions of dollars from Medicaid spending, New Jersey is getting national attention for its proposal.Opponents say it's an unprecedented and draconian attempt to balance the budget on the backs of society's most vulnerable people.At issue is a $540 million cut to state Medicaid funding in Gov. Chris Christie's proposed budget for next year. It would drop eligibility for new adult enrollees to about 25 percent of the poverty level.But critics worry that the state can't be sure it will save money. And since state money is matched by federal money, any cut to Medicaid spending means fewer dollars coming into New Jersey.Medicaid provides health care to low-income people at risk due to disability, age, chronic illness and other circumstances.
