This is an episode from the Vox daily news podcast, Today, Explained. Host Noel King spoke with OTM regular, Rick Perlstein. As a historian of US politics he is often called upon to draw comparisons between today’s events and those of the past. This year in particular, the echoes with 1968 are unavoidable: the DNC is again in Chicago, there are protests outside (this time its about Gaza, then it was the Vietnam War).
