Parties, Partisanship, and Public Policy in the Pennsylvania Legislature

A significant result of the report “Toward A More Responsible Two-Party System” has been the marked growth of interest in the American party system. It is nevertheless true that our knowledge about the way in which party systems function is far from complete. An area promising fruitful research and presenting many hypotheses susceptible of systematic inquiry is that of the role of party organizations in the legislative process.It is the purpose of this article to examine the legislative role of political parties in the Pennsylvania General Assembly; more precisely, to measure their influence in the formation of the state's public policies in one session of the legislature. The most recent completed session at the time of this study was that of 1951—the longest session in state history.In order to evaluate the impact of party upon legislation, the concept of a “party vote” has been used. This is merely an operating definition by which to measure differences in party attitudes on questions subjected to roll-call votes on the floor. The assumption was made that the interests of the parties can be established best by analyzing the voting behavior of their membership. Questions to which partisan significance is attached will find the parties aligned against each other.
