Mitt Romney and running mate Paul Ryan are telling Ohio voters that President Barack Obama still doesn't have any idea how to salvage the tough economy he inherited.
The Republican duo campaigned near Columbus on Saturday as Obama launched a new line of criticism about what they would do to Medicare. Outside the rally, protesters heckled the presumptive GOP ticket about their plans for seniors' health care.
Ryan says one in six Americans is living in poverty. He says the country is done being fooled by Obama's promises to change Washington.
The rally is expected to be Romney's last public appearance before the Republican National Convention opens next week in Tampa, Fla.
