Gerrymanders And Theories Of Law Making: A Study Of Legislative Redistricting In Illinois, Michael C. Herron, Alan E. Wiseman

Dartmouth Scholarship

Redistricting politics in Illinois provide a novel opportunity for testing competing theories of law making. With this in mind, we demonstrate that the post-2000 Census redistricters in Illinois, dominated by Democrats, strategically reshuffled district demographic profiles in an attempt to convert relatively liberal Republican districts to conservative Democratic districts in the state Senate while decreasing and increasing the ideological diversity of the Democrats and Republicans, respectively, in the House. Such reshufflings suggest that legislative politics in Illinois are conducted in a manner consistent with vote-buying theories of coalition formation.
