A New Measure of Group Influence in Presidential Elections: Assessing Latino Influence in 2008

The importance of the Latino electorate has been the subject of both academic inquiry and media discourses. The question of Latino influence is frequently limited by an approach that focuses on single variable considerations (e.g., voter turnout or ethnic-targeted campaign spending) that are often contest-specific idiosyncrasies. Relying on theoretically appropriate concepts, the authors measure Latino political influence as a function of three factors: in-group population traits, electoral volatility, and mobilization. Using the 2008 presidential election, the authors demonstrate the utility of incorporating a multifaceted measure that accounts for the contemporary complexity within the electoral environment. Because this framework is rooted in theoretical concepts, as opposed to discrete group or contest characteristics, it may be applied to any "influence group" in different electoral settings. Data are culled from several publicly available outlets, making it possible for scholars to replicate these measures and further investigate questions associated with group influence in American politics.
