Maybe the Dems are saving it (broader student loan forgiveness) for a 2016 campaign issue...
I had heard of some loan forgiveness programs so I googled it.

Just going over a couple of links quickly it appears there are a number of different student loan programs and some of them have forgiveness provisions.
Here is another interesting link.
