WASHINGTON (AP) — Driven by frustration over deficits and debt, Republican conservatives are pushing a politically risky move to permit painfully large automatic spending cuts to strike the Pentagon and domestic programs alike in an effort to force Democrats into making concessions on the budget.

It's a remarkable turnabout from last year, when GOP leaders were among the loudest voices warning of dire consequences for the military and the economy if more than $100 billion worth of across-the-board cuts were allowed to take effect. Now, even as defense hawks fume, Republicans see the strategy as their best chance of wringing cuts from costly government benefit programs like Medicare that President Barack Obama and his Democratic allies have been reluctant to touch.

The move is fraught with risk. Some $43 billion would be cut from the Pentagon budget between March and October if battling Democrats and Republicans can't agree on an alternative. Equal cuts would hit domestic programs, although the health care programs that are major drivers of future deficits are largely exempt.
