State agencies and bureaucrats, consider yourself warned.

Gov.-elect Andrew Cuomo vowed yesterday to swing the ax once he takes office in January to slash government waste as the state prepares to plug a projected $9 billion budget gap.

He also backed Gov. Paterson’s decision to convene an emergency session of the Legislature on Monday to trim a $315 million deficit in the current budget.

“When people say, ‘You can’t cut the state budget,’ the implication being this is a finely tuned Swiss watch and there is no waste or fraud or abuse in state government. That’s just not true,” Cuomo said after donating turkeys to the New York City Rescue Mission in lower Manhattan.
