CHAPEL HILL, N.C. -- President Barack Obama went after the college vote Tuesday, pitching cheaper student loans as he courted the one age group where he has a decided advantage over Republican rival Mitt Romney. The twist? Romney, too, has endorsed the idea, though it's unclear whether deficit-leery Republicans in Congress will go along.
In the race for the White House, the Obama and Romney campaigns see huge opportunities to court younger voters. This week, their efforts are focused on the millions of students and their parents who are grappling with college costs.
Obama crossed the nation, from North Carolina to the foothills of the Rocky Mountains in Colorado, to sell his message to college students. Both stops, as well as the one he will make Wednesday in Iowa, came in states vital to his re-election bid.
Obama told students at the University of North Carolina that he and first lady Michelle Obama had "been in your shoes" and did not pay off their student loans until eight years ago.
"I didn't just read about this. I didn't just get some talking points about this. I didn't just get a policy briefing on this," Obama said. "We didn't come from wealthy families. When we graduated from college and law school, we had a mountain of debt. When we married, we got poor together."
Obama's emphasis on his personal experience set up a contrast with Romney, whose father was a wealthy auto executive. It's a point Obama is sure to return to during this summer's campaigning.
Late Tuesday, Senate Majority Leader Harry Reid, D-Nev., introduced legislation that would keep the interest rate for subsidized loans for poorer and middle-class students at their current level for another year at a cost of $5.9 billion. The timing is important because the rate will double from 3.4 percent to 6.8 percent July 1 without intervention by Congress, an expiration date chosen in 2007 when a Democratic Congress voted to chop the rate in half.
The Federal Reserve Bank of New York has estimated about 15 percent of Americans, or 37 million people, have outstanding student loan debt. The bank puts the total at $870 billion, though other estimates have reached $1 trillion. About two-thirds of student loan debt is held by people younger than 30.
Members of both parties are assessing ways to cover the costs and then gain the votes in the House and Senate. Both parties have a political incentive to keep the rates as they are.
Senate Minority Leader Mitch McConnell, R-Ky., said Tuesday: "I don't think anybody believes this interest rate ought to be allowed to rise." He added, "The question is how do you pay for it, how long do you do the extension."
Under the Democratic plan, the measure would be paid for by closing a loophole that lets owners of privately owned companies called S corporations avoid paying the Social Security and Medicare payroll tax on part of their earnings. It would apply to such companies with incomes of more than $250,000. The higher payroll taxes also would be required for some law firms, doctors practices and other professional services partnerships.
Congressional Republicans, however, were panning the idea of paying for the student loan plan with higher payroll taxes on those companies' owners.
"I don't think the temporary interest rate cut should expire this year," McConnell said. "But the way to prevent that is not by raiding Social Security and Medicare while making it more difficult for small businesses to hire college students already struggling in the Obama economy."
Romney said this week he agrees the loan rates should not be raised, coupling that stance with criticism of Obama's economic leadership.
"Given the bleak job prospects that young Americans coming out of college face today, I encourage Congress to temporarily extend the low rate," Romney said in a statement.
Some conservative activists have denounced Romney's decision to match Obama's position on student loan rates.
"Mitt Romney is going to sell out conservatives in his party" to improve his chances in the November election, Michael Brendan Dougherty wrote in a blog carried by sites including Free Republic.
By taking on student debt, Obama spoke to middle-class America and also targeted a growing economic burden that could hamper the national recovery.
While leaning on Republicans in Congress to act, he also sought to energize the young people essential to his campaign -- those who voted for him last time and the many more who have turned voting age since then. Obama urged students to go to social media sites such as Twitter to pressure their lawmakers to prevent the interest rates on the loans "from shooting up and shaking you down."
The blurring between Obama's official and campaign events emerged here in Tar Heel country, with Obama encouraging students to give him an "Amen" at times (they did) and the crowd also giving him an unsolicited chant of "Four more years!" Obama soaked in the youth vibe on campus, where he also appeared in a taping of "Late Night with Jimmy Fallon."
Romney supporters said Obama's policies had hurt younger voters and questioned whether Obama could garner the same amount of support as in 2008.
"Young people are sitting here three and a half years later, and they're not better off," said Alex Schriver, chairman of the College Republican National Committee.
Obama also spoke Tuesday at the University of Colorado at Boulder, and then at the University of Iowa on Wednesday. All three schools are in states that Obama carried in 2008, and all three states are considered among the several that could swing to Obama or Romney and help decide a close 2012 election.
Before his speech on the Colorado campus, Obama went after students in a likely place to find them -- a bar. He stopped in Boulder at "The Sink," shaking hands with young people enjoying beers and burgers. One woman said she wanted to start a restaurant based on cheese fries. "Sounds good," he said. Another woman accidentally spilled yogurt on Obama and a Secret Service agent, much to her embarrassment.
Obama carried voters between the ages of 18-29 by a margin of about 2-to-1 in 2008, but many recent college graduates have had difficulty finding jobs. That raises concerns for Obama about whether they will vote and volunteer for him in such large numbers again.
Obama said allowing the interest rates to double this summer would hurt more than 7 million students, costing the average student $1,000 and amounting to a "tax hike" for those students and their families.
"Anybody here can afford to pay an extra thousand dollars right now?" Obama asked to jeers from the crowd. "I don't think so."
