An increasing number of citizens now live in sprawling yet interconnected urban environments, as diversified metropolitan geographies eclipse the centuries-old divide between urban and rural areas. This changing landscape has also transformed local sources of electoral politics, and the resulting patterns of electoral support and participation have shifted partisan competition to the right. This volume undertakes the first international comparative analysis of metropolitan political behavior, termed the "metropolitanization of politics," providing a powerful new thesis for explaining a number of recent shifts in political preferences and voting habits.
