The United States is experiencing remarkable demographic changes that are having an important impact on the American electorate. As the minority share of the voting-eligible population continues to grow, the political clout of non-Hispanic whites will further decline. The 2012 election demonstrated that the Democratic Party can secure an Electoral College victory even when it loses badly, in the aggregate, among non-Hispanic whites. This does not mean that white voters are unimportant, however. The political behavior of whites in the decades ahead will largely determine the direction of American politics. This book examines the political behavior of non-Hispanic whites. It considers the trends within the white vote, how white voters differ geographically, and the primary fault lines among white voters. It also examines how white political behavior changes in response to diversity. It considers whether or not the day is approaching when whites consolidate into a largely homogenous voting bloc, or whether whites will remain politically heterogeneous in the decades ahead Whereas other books have examined the political behavior of specific social classes within the non-Hispanic white community (working class whites, for example), this is the first book to examine whites as a whole, and provide a useful summary of recent trends within this group and thoughtful speculation about its future.
