Policy Space and Voting Coalitions in Congress: The Bearing of Policy on Politics, 1930-1954

Katznelson, Ira; Lapinski, John; Razaghian, Rose

The question of how the substance of politics helps shape legislative coalitions and bases of support has been displaced from the center of studies of Congress since the publication of pioneering work in the 1960s and early 1970s. Seeking to revive this research program, the authors apply an original coding scheme in tandem with a factor analytic analysis of voting and policy space to the period spanning the last years of the Hoover presidency to the start of Eisenhower's. Investigating legislator parameters—the dimensions of voting space—and roll call parameters—the dimensions of policy space—the paper confirms the strong independent impact of the substance of policy on the political decisions of legislators and reveals an issue-specific concatenation of party and region that altered over the course of the period.
