Congressional Primaries and the Politics of Representation explores the ways in which congressional primary elections appear to be changing in the face of electoral and congressional politics. The prominent contributors examine how primary elections influence the types of candidates who run, the support they receive, the positions they take, the resources they spend, the media coverage they receive, and the type of party nominees that prevail. All of these factors have significant implications for congressional general elections, the political parties, interest groups, and the day to day representation of constituents by congressional incumbents in the United States.
