Republican vice presidential candidate Paul Ryan is kicking off another busy week for candidates on the campaign trail in Ohio. Ryan is scheduled to speak at a rally near the Toledo airport on Monday. It's his second trip to the state in little over a week. Both President Barack Obama and Republican challenger Mitt Romney will be in Ohio on Tuesday. Obama will attend a rally in Columbus on the Ohio State University campus. Romney will be at a campaign event Tuesday night in Cuyahoga Falls and then stay for a couple more stops in central Ohio on Wednesday.
