(CNN) - This week President Obama did a swing through some college campuses talking about student loan debt. The immediate issue is the 3.4% interest rate on federal student loans. It's set to double July 1 unless Congress acts. Keeping the rate low in this still weak economy is, as the president said, a no-brainer. Even his opponent Mitt Romney has endorsed it. But the larger problem - mounting college costs and a cumulative $1 trillion in student loan debt — remains untouched.
Some recent polls have shown that support for Obama among young voters, once Obama's enthusiastic fans, may be waning in this election compared with four years ago. Student loans are seen by some as the president's chosen key to regaining their hearts. But really, the issue has been raised for him by the Occupy movement, gearing up this May 1 with a new set of actions focusing on the cost of college and the depredations of the student loan industry.
Additionally, almost 700,000 people have signed a petition sponsored by MoveOn.org for student loan forgiveness, started by lawyer and student-loan debtor Robert Applebaum. And the Student Loan Forgiveness Act of 2012, introduced by U.S. Rep. Hansen Clarke, D-Michigan, last month, is aimed at offering relief.
