>> i think it's a jobless recovery. if it's a recovery at all. it really doesn't look like a recovery. >> reporter: the obama campaign hit back with vice president biden campaigning in ohio, attacking romney's economic plan. >> folks, we've seen this movie before. and we know how it ends. it ends in a catastrophe for the middle class. >> reporter: health care is also being debated on the trail with romney raising some eyebrows. for months, the gop hopeful said he would repeal the president's health care law but now -- >> i'm not getting rid of all of health care reform, of course. there are a number of things that i like in health care reform that i'm going to put in place. one is to make sure that those with preexisting conditions can get coverage. >> reporter: today, romney heads to the crucial state of ohio, no republican has ever won the white house without winning the buckeye state. without ohio, romney would need to win every battleground state after the white house. for the first time in four months, the obama campaigned pulled ahead of the romney team in fund-raising.

>> look at the guy. we also have one tragic note to pass on from the campaign trail. a motorcycle officer working security for the president's motorcade in west palm beach was hit by a pick-up truck and killed. the officer who was a 20-year veteran of the jupiter police department was helping shut down i-95, ahead of the motorcade, when he was struck. the white house said the president did not see the accident. and iraq has just suffered one of its deadliest days since withdrawal of u.s. troupes. more than 90 people were killed in nearly two dozen shootings across the countries and hundreds of others wounded. no one has claimed responsibility, but the government is blaming al qaeda. and a top al qaeda leader in africa has been killed in a car crash. nabil makhloufi was born in algeria and had been a longtime leader of the terror group. the accident took place in the republic of mali which is located in western africa.
