In the final episode of this five-part series on the Iowa caucuses, we take you back to Iowa one last time for the final sprint before caucus day. We explore how impeachment is impacting the campaigns, attend events with major surrogates like Alexandria Ocasio-Cortez, and talk with Iowa elected officials about who they will endorse. Finally, we’ll walk you through the results of our exclusive Iowa poll, map out possible paths to victory for the leading candidates, and check in one last time with the true heroes of these campaigns, the field organizers. This series is hosted by Tommy Vietor and produced by Pineapple Street Studios.
