Younger voters, including millions of college students, were a major factor in electing President Barack Obama in 2008. He is hoping they will rescue him again this year.
Obama has an issue - student loan rates - to use in wooing college students as he did in three campus visits last week.
Student loan interest rates are set to double, going from 3.4 percent to 6.8 percent, under a law enacted by a Democrat-controlled Congress a few years ago.
Obama has been criticizing the change, though it would increase average loan repayments by only about $8 a month.
Just one thing he isn't telling students: The interest rate hike wouldn't affect most of them. Their loan interest rates are already locked in.
