UNITED STATES -- After erasing Hillary Clinton's once-substantial lead among superdelegates, Barack Obama is now beginning to outline his campaign points against Republican rival John McCain.

Speaking in Oregon, Obama says the fall election will be more about specific plans and priorities than about questions of political ideology or who is more patriotic.

This weekend, Obama picked up four superdelegates to take the lead, one of whom had originally endorsed Clinton. He heads to Missouri on Tuesday and he plans to make stops in Michigan and Florida on a later date.

Meanwhile, Hillary Clinton spent Saturday campaigning in Manhattan. At a Mother's Day themed fundraiser, the New York Senator said it would be exciting to have a mother as president. She barely mentioned Barack Obama except to knock his positions on health care and the gas tax.
