NEW YORK - June 7, 2010 - Having counted on Washington for money that may not be delivered, at least 30 states will have to close larger-than-anticipated shortfalls in the coming fiscal year unless Congress passes a six-month extension of increased federal spending on Medicaid.

Governors and state lawmakers, already facing some of the toughest budgets since the Great Depression, said the repercussions would extend far beyond health care, forcing them to make deep cuts to education, social services and public safety.

For instance, Governor Edward G. Rendell of Pennsylvania penciled $850 million in federal Medicaid assistance into the revenue side of his state’s ledger, reducing its projected shortfall to $1.2 billion. The only way to compensate for the loss, he said in an interview, would be to lay off at least 20,000 government workers, including teachers and police officers, at a time when the state is starting to add jobs.

“It would actually kill everything the stimulus has done,” said Rendell, a Democrat. “It would be enormously destructive.”
