Today we're talking RNC and DNC. The committees, not the conventions. What do they do? Who decides who chairs them? And what does it mean to a national committee when someone can post a message on social media that has more impact than thousands of mailbox flyers?

Today's guests are Boris Heersink and Marjorie Hershey, who take us from a few folks setting up a convention to a massive organization that tries (and sometimes fails) to wrangle a party's identity.
