A recent Associated Press survey found that more than half of the states — 33 — are currently dealing with a budget shortfall or expect to confront one in the coming fiscal year. Experts say state economic growth has been slower than expected, with revenue in some places failing to meet projections or keep up with rising spending needs. ... Medicaid costs are contributing to budget gaps in Massachusetts, Maryland, Mississippi, New York and Rhode Island. Other states are dealing with increasing spending demands in education and health care.
