Replication data for: Challenges to the American Two-Party System: Evidence from the 1968, 1980, 1992, and 1996 Presidential Elections

Students of electoral behavior point to party decline, whereas analysts of party organization see growth and transformation. Analyses of the 1968, 1980, 1992, and 1996 National Election Study surveys are used to determine whether support for Wallace, Anderson, and Perot resulted from dissatisfaction with the current two-party system.

We find that there has been little erosion of support for the major political parties between 1968 and 1996. Americans with low levels of support for the major political parties were more likely to support Wallace in 1968 and Perot in 1992 and 1996. But to a large extent, support for Wallace, Anderson, and Perot resulted from dissatisfaction with the major-party candidates.
