The "Palin Effect" in the 2008 US Presidential Election

Using data from the American National Election Studies, this article addresses whether the Sarah Palin affected vote choice in 2008. Findings indicate not only that evaluations of Palin were a strong predictor of vote choice-even when controlling for confounding variables-but also that Palin's effect on vote choice was the largest of any vice presidential candidate in elections examined dating back to 1980. Theoretically, the article offers support for the proposition that a running mate is an important short-term force affecting voting behavior. Substantively, the article suggests that Palin may have contributed to a loss of support among "swing voters.".
