Since 1952, the social bases of the Democratic and Republican parties have undergone radical reshuffling. At the start of this period southern Blacks favored Lincoln's Republican Party over suspect Democrats, and women favored Democrats more than Republicans. In 2020 these facts have been completely reversed. A Tale of Two Parties: Living Amongst Democrats and Republicans Since 1952 traces through this transformation by showing:How the United States society has changed over the last seven decades in terms of regional growth, income, urbanization, education, religion, ethnicity, and ideology;How differently the two parties have appealed to groups in these social cleavages;How groups in these social cleavages have become concentrated within the bases of the Democratic and Republican parties;How party identification becomes intertwined with social identity to generate polarization akin to that of rapid sports fans or primitive tribes.A Tale of Two Parties: Living Amongst Democrats and Republicans Since 1952 will have a wide and enthusiastic readership among political scientists and researchers of American politics, campaigns and elections, and voting and elections.
