One-Time Democratic Nominee Michael Dukakis On This Year's Convention

One of the few people who can really understand what Hillary Clinton is experiencing as she's about to become the Democratic party's presidential nominee is a former governor of Massachusetts: Michael Dukakis. He was the party's unsuccessful nominee in 1988.

Dukakis travels to Philadelphia later this week for the end of the convention. We caught up with him in his office at Northeastern University and asked him about the leaked emails that show party leaders tried to undermine the campaign of Bernie Sanders.
