COLUMBUS, Ohio — Pressing a contrast with his rivals for the White House, President Barack Obama expanded his critique of the Republican budget blueprint to focus on education policy, arguing Mitt Romney would reverse his administration's policies to boost education despite the consequences to the economy.

For the president, who addressed about 3,300 supporters at Capital University on the eastern edge of Ohio's capital city, the policy wasn't just about politics. It was also personal.

Drawing on his and his wife's struggles to pay off student debts, Obama said at the outdoor rally that the concept of affordability was not unfamiliar.

“We've been in your shoes,” he said. “I'm only standing before you because of the chance that my education gave me. So I can tell you with some experience that making higher education more affordable for our young people — it's something I've got a personal stake in.”

Democratic officials call education “one of the most important economic issues facing our nation.” The stop was the first of three in the next days at either college or high school settings.

The president's campaign is eager to highlight how a budget proposal offered in Congress by Rep. Paul Ryan, the GOP vice presidential pick, would affect key areas beyond Medicare, the focus of initial skirmishing after Romney added the Wisconsin lawmaker to the ticket.

But the campaign is also seeking to reignite enthusiasm among younger voters, like the ones present at the rally and the ones he interacted with at an earlier unscheduled stop on the campus of Ohio State University.

The Romney campaign responded to Obama's focus on education by saying that under his leadership, “too many young Americans are suffering from higher college costs, more debt, and a lack of good jobs when they graduate.”

“Today's policies are just more of the same from a president who hasn't fixed the economy or kept his promises to the young people who supported him four years ago,” Romney-Ryan spokewoman Amanda Henneberg said. “The Romney-Ryan plan will deliver 12 million new jobs to help recent graduates — and all Americans — enjoy a more prosperous future.”
