With the question of will Joe Biden run still up in the air, AirTalk asks: Should he?

In early August, AirTalk debated whether Joe Biden would make a run for the presidency in 2016 or not. To this point, the vice president has stayed mum on the decision, and has even hinted that he might not be able to put himself completely into a presidential run. Guests include Julian Zelizer, Professor of history and public affairs at Princeton University and a fellow at the New American Foundation.
