Episode 4 of The Bellwether looks at what’s happened since Donald Trump won Suffolk County so decisively in 2016.

This episode is a deep dive -- featuring the county Democratic and Republican bosses, an intriguing turnout theory from a Democratic superPAC, and a trip back in time to the halcyon days of duck-hunting, bow-tie wearing Long Island Rep. Otis Pike, who has something to teach us about how challengers win on Long Island.
