Republican presidential rivals are calling for deep cuts in federal spending that don't hurt millions of Americans who receive government services.
That was one of the messages on Dec. 12 in an Iowa debate happening a little more than three weeks before the state's caucuses provide the first test of the campaign.
Former Massachusetts Governor Mitt Romney, who has seen his lead in Iowa vanish in recent polls, says the government programs that need to go first are the ones that don't work.
Former New York Mayor Rudy Giuliani, meanwhile, called for across-the-board cuts of up to 15-percent, including reduced federal spending on health care.
Former Arkansas Governor Mike Huckabee has overtaken Romney in public surveys of likely caucus goers in Iowa.
