Two steps forward, one step back? Bias in the 2008 presidential election

The candidates running during the 2008 presidential campaign were the most diverse in America's history. Prior to this historic election, female and minority candidates had little success in pursuing the presidency. Barack Obama's victory signals a decline in those barriers. Yet some groups, especially religious ones, continue to face barriers, including Atheists, Mormons and Muslims. The paper takes a close look at bias in presidential voting. This examination will provide an opportunity to consider new hypotheses about why barriers remain, shedding light on the nature and extent of bias within the American public. We consider social desirability, ideology, social contact, and group threat explanations. To test our ideas, we rely on list experiments using national representative samples in 2007 and in 2008. These data provide a unique opportunity to advance our understanding of the 2008 election, in particular, and the role of bias, in general. The results also offer some insight into future presidential elections. (C) 2011 Elsevier Ltd. All rights reserved.
