It must be difficult for Democratic National Committee Chair Debbie Wasserman Schultz. After all, she’s watching her chosen candidate, Hillary Clinton, face a legitimate struggle for the party nomination against a man who says he’s a socialist, serves as an Independent in the Senate, and is running for the Democratic nomination for the White House. He’s an old white dude and the Millennials are crazy about him. What’s going on?

Leave it to MSNBC’s Chris Matthews, then, to put Schultz on the spot and ask her to define the difference between a Democrat like her and a socialist.
