Party of the People analyzes the transformation of the Republican coalition under Donald Trump, arguing that the 2016 and 2020 elections represented the most significant demographic realignment in decades. Patrick Ruffini, a Republican pollster and data analyst, marshals extensive survey data to demonstrate that Trump assembled support from working-class voters across racial lines—a combination that defied conventional political categories. The book examines how Trump's economic nationalism and cultural populism appealed to Hispanic voters in South Texas, Vietnamese and Filipino communities in California, and working-class African Americans in Northern cities. Ruffini traces the historical roots of this realignment, showing how Democratic focus on college-educated professionals created an opening among voters who felt left behind by globalization and cultural liberalism. He also confronts the tensions within this new coalition, particularly between populist and traditional conservative factions. The analysis provides both Republicans and Democrats with important insights about the changing nature of partisan identity in America. For readers seeking to understand the political landscape beyond simple red-versus-blue narratives, this book offers a data-driven exploration of how class, culture, and ethnicity interact in contemporary politics.
