Over the second half of the 20th century, American politics was reorganized around race as the tenuous New Deal coalition frayed and eventually collapsed. What drove this change? In The Cities on the Hill, Thomas Ogorzalek argues that the answer lies not in the sectional divide between North and South, but in the differences between how cities and rural areas govern themselves and pursue their interests on the national stage. Using a wide range of evidence from Congress and an original dataset measuring the urbanicity of districts over time, he shows how the trajectory of partisan politics in America today was set in the very beginning of the New Deal. Both rural and urban America were riven with local racial conflict, but beginning in the 1930s, city leaders became increasingly unified in national politics and supportive of civil rights, changes that sowed the seeds of modern liberalism. As Ogorzalek powerfully demonstrates, the red and blue shades of contemporary politicalgeography derive more from rural and urban perspectives than clean state or regional lines-but local institutions can help bridges the divides that keep Americans apart.About the Author: Thomas K.
