Democratic presidential hopeful Martin O’Malley on Wednesday put forward an ambitious five-year goal of allowing students to graduate debt-free from public colleges and universities across the country.

The proposition is deeply personal for O’Malley: Aides say he and his wife have already incurred $339,200 in loans to put the two eldest of their four children through universities. And college affordability was a leading priority for O’Malley during his tenure as Maryland’s governor.

The issue is one being talked about a lot these days by Democrats, including the party’s other White House candidates, as more and more students enter the workforce with hefty debt loads.
