Considered a microcosm of the nation, the state of Illinois stretches almost four hundred miles from its northern limit at the Wisconsin line to its southern tip at Cairo, nestled between Kentucky and Missouri. Its political culture is as intriguing as the state is long. Illinois has produced presidents and leading members of Congress. It also has a long history of political corruption, including, in recent years, the federal indictments of two consecutive governors. The population of the state is exceptionally diverse, with a significant number of new immigrants. Its political allegiance, once firmly Republican, has trended ever more Democratic. Illinois can be divided neatly into three distinct regions: Chicago, the suburban collar surrounding the city, and the ninety-five downstate counties. Based on the research and experience of respected veterans of Illinois politics, this book shows how the government runs, how politics operates, and what obstacles and opportunities exist for change. It explains how power is exercised and how parties compete for it. For engaged citizens, scholars, and students, Illinois Politics: A Citizen's Guide is a timely and much-needed roadmap for positive change.
