Transformation and polarization: The 2008 presidential election and the new American electorate

Along with the unpopularity of President Bush and the dire condition of the U.S. economy, changes in the composition of the American electorate played a major role in Barack Obama’s decisive victory in the 2008 presidential election. The doubling of the nonwhite share of the electorate between 1992 and 2008 was critical to Obama’s election as African-American and other nonwhite voters provided him with a large enough margin to overcome a substantial deficit among white voters. In addition, voters under the age of 30 preferred Obama by a better than 2–1 margin, accounting for more than 80 percent of his popular vote margin. Despite the overall Democratic trend, the results revealed an increasingly polarized electorate. Over the past three decades the coalitions supporting the two major parties have become much more distinctive geographically, racially, and ideologically. The growth of the nonwhite electorate along with the increasing liberalism and Democratic identification of younger voters suggest that a successful Obama presidency could put the Democratic Party in a position to dominate American politics for many years. However, these trends appear to be provoking an intense reaction from some opponents of the President. The frustration and anger displayed at “tea party” demonstrations and town hall meetings may reflect not just discomfort with Barack Obama’s race but the perceived threat that Obama and his supporters represent to the social status and power of those on the opposing side.
