Objective. This study examines the backgrounds, political attitudes, issue preferences, and political participation of congressional donors who contribute 200 or more to congressional campaigns. Methods. We use a nationwide survey of more than 1, 000 donors and analyze differences among these individuals using cluster analysis. Results. Although these significant donors are economic elites, we find they are not monolithic in their political views and attitudes. There are significant cleavages in the donor pool across and within the two major parties on various political issues and involvement in different political organizations. Perhaps most important, we find that the most active donors hold the most ideologically extreme political views. Conclusions. The results suggest that the sharp cross‐party differences and the meaningful variations within party coalitions, combined with the greater activity of more ideologically extreme donors, contribute to and reflect party polarization.
