Unearths the religious and cultural roots of a powerful political machine that empowered some everyday Chicagoans but ruled all of the city for decades. In politics, clout is essential. Too often, it determines whether insider access is granted or denied, favors are given or withheld, and payoffs are made or received. But Chicago clout, as we know it today, is even more potent than that--it's the absolute currency of a social, cultural, and political order that is self-reinforcing and self-dealing. Or, at least, it was. In Clout City, award-winning historian Dominic A. Pacyga reveals how cultural, ethnic, and religious forces created this distinctive system--and ultimately led to its collapse. Tracing clout's origins in the Irish Catholic-dominated working-class neighborhood of Bridgeport, shaped by De La Salle Institute and home to the legendary Daley family, Pacyga shows how communal ties can be a force for good and also the deepest wellspring of corruption. He maps Chicago's unique politics to its remarkable history, from the Great Fire of 1871 through its rise and decline as an industrial center to its emergence as a global city in the early twenty-first century. With deep research and firsthand experience from a lifetime in the city, Pacyga argues that Chicago's politics is understood best as a mixture of cultural and religious influences and more worldly pursuits, exploring how both Jewish and Catholic communalism played central roles in the creation and sustenance of the Chicago machine. Chicago's politics today aren't as defined by its distinctive brand of clout. But they are shaped by clout's decline and the ghost of the machine. Pacyga's tour of the city's multilayered past is an indispensable guide to its present and future.
