Premonitions of Election Day violence abound, especially with the growing visibility of extremist militia groups. This week, On The Media looks at a little-known app fueling those groups’ recruitment and organizing. Plus, why skepticism of election forecasts might be a good thing. And, how election coverage has changed (and stagnated) since 2016.
