It's one of the most democratic aspects of our nation, not to mention extremely recent. In this episode we explore the snarled history of how we select party nominees; from delegates to superdelegates, and from gymnasiums in Iowa to booths in New Hampshire.

This episode features political scientists Bruce Stinebrickner (DePauw University) and Alvin Tillery (Northwestern University), NPR's Domenico Montanarro, Iowa Public Radio's Kate Payne, and Lauren Chooljian from NHPR.
