This research examines the effect of disgruntlement among primary and caucus voters who supported U.S. presidential nomination losers—a potentially divisive nomination process. I analyze the general election voting behavior of primary and caucus voters in the 2008 presidential election to determine if differences exist between supporters of the winning nominee in each party and backers of other candidates who also sought the nomination. A multivariate analysis of the determinants of “loyal party vote” suggests that Clinton and Edwards supporters showed a significantly higher degree of defection in the general election, although this behavior did not occur among people who voted for Romney or Huckabee in their state's primary or caucus.
