Jeff Segal (SUNY--Stony Brook, Poli Sci) reminded me about the following Call for Papers.
"Ask your favorite political scientist what the biggest political science conference is, and she'll tell you it's the American Political Science Association. Ask her what the best political science conference is, particularly for empirical work, and she'll tell you it's the Midwest Political Science Association meeting, held every April in the beautiful Palmer House in Chicago.
The Midwest Political Science Association, like most academic associations, charges higher conference registration rates for nonmembers than to members. Hoping to continue to increase attendance by people outside of political science and related fields at its annual meeting, the Association will begin charging registrants who 1) have academic appointments outside of political science or related fields (policy, public administration and political economy) and 2) do not have a PhD in political science or the same related fields, conference registration rates equal to member registration rates.
