In this installment of the 538 Politics podcast, the crew explores the thorny negotiations surrounding immigration and border security in Washington. Galen talks to Carlos Odio, co-founder of Equis Research; Rachael Bade, author of POLITICO Playbook; and Leah Askarinam, 538 politics reporter. Together, the crew discusses evolving public sentiment on immigration, explores proposed policy changes and guesses what Americans think about the political landscape right now. Later in the show, Galen is joined by G. Elliott Morris, 538’s director of data analytics, to uncover more about how 538's pollster ratings are determined and reveal what are the best pollsters in America.Learn more about your ad choices.
