Issue Politics in a Polarized Congress

The standard explanation for increasing party polarization in Congress is based on factors that would affect all policy issues simultaneously. We show that this has not happened. We examine the dimensionality of legislative choice in the House of Representatives, scaling eighteen issues in each Congress from 1965 through 2004. We detect considerable variability in issue dimensionality, an evolution in the structure of choice over time, and changes in the relationship between party unity and issue dimensionality. Our findings suggest that polarization has occurred on an issue-by-issue basis, reinvigorating the debate over the role of policy substance in shaping congressional politics.

The Politics of Choice Reconsidered: Partisanship, Ideology, and Minority Politics in Washington’s Charter School Initiative:

Charter schools enjoy support among Republican and Democratic lawmakers in states and Congress, but little research has examined their support among the electorate. We take advantage of Washington’s 2012 charter school ballot initiative—the first voter-approved charter initiative in the United States—to shed light on the politics of school choice at the mass level. Because in-depth, individual-level voter data are often unavailable in state-level elections, we leverage extensive precinct- and district-level data to examine patterns of support and opposition toward the charter school initiative, focusing on how partisanship, ideology, and demographic factors serve to unify or divide voters. Our analysis reveals that the coalition of supporters cut across usual partisan and demographic cleavages, producing somewhat strange bedfellows. This finding has important implications for the strategies advocacy groups may consider as they seek to expand or limit school choice programs via ballot initiatives as opposed to the statehouse, and provides suggestive evidence regarding the evolving shapers of voter support for school choice and ballot initiatives more generally.
