The Real (Lack of) Difference between Republicans and Democrats: A Computer Word Score Analysis of Party Platforms, 1996–2004

Abstract

For years voters and political pundits have grumbled about the lack of real choice between Republicans and Democrats. Scholars have examined party behavior and suggested reasons for concern. Determining whether there is a real ideological and policy difference between U.S. political parties, and the nature of that difference, is important for political science and for democratic politics generally. Ultimately, democracy is about choices, and where choices are few, democracy is degraded. One way to examine the choices that political parties offer voters is by assessing their political platforms. Even in an era of candidate-centric politics, political party platforms spell out the general programs offered by the parties, and the platforms are heavily influenced by the policy positions of the candidates themselves. In addition, the political platform is the one document that spells out the entire program of the party. Individual candidate speeches capture only snippets (at best) of the policy choices offered to voters. Recent innovations in computerized content analysis make it possible to analyze large bodies of text such as party platforms in a systematic way by treating words as data, then analyzing them statistically.
