Romney focuses on Obama after victories

Mitt Romney is turning away from his primary opponents and towards Democratic President Barack Obama after sweeping three more Republican contests.

“There is a basic choice before us,” Romney said to cheering supporters in Milwaukee. “Our different visions for America are the product of our values and our life experiences.”

Romney’s victories in Wisconsin, Maryland and the district of Columbia widened his delegate lead and all but handed him the title of presumptive Republican nominee.
