Howard Dean Says He Will Consider a 2016 Presidential Run

But only if no other candidate is speaking about issues that he thinks are important

Former Vermont governor Howard Dean, who in 2004 lost his bid to become the Democratic presidential nominee, says he'll consider another run for president in 2016.

Dean — an outspoken liberal — told CNN's Peter Hamby that he will run if other candidates aren't addressing the issues that are important to him.

"I am not driven by my own ambition," Dean said. "What I am driven by is pushing the country in a direction that it desperately needs to be pushed, pushing other politicians who aren't quite as frank as I am who need to be more candid with the American people about what needs to happen. I am not trying to hedge. It's a hard job running. It's really tough. I am doing a lot of things I really enjoy. But you should never say never in this business."
