As the 2024 US election goes into the final day, a poll giving Kamala Harris a lead in the historically Republican state of Iowa has bolstered the Democrats. Is momentum really with her? And what appears to be the most important issue to voters - the economy, or abortion rights? Guest host Kate Andrews speaks to John Rick MacArthur, president and publisher of Harper's Magazine, about his views on America's election process from postal voting, trust in the system, and whether the electoral college needs reform. Produced by Patrick Gibbons.
