Abstract
In 2008, a group of uninsured low-income adults in Oregon was selected by lottery for the chance to apply for Medicaid. Using this randomized design and state administrative data on voter behavior, we analyze how a Medicaid expansion affected voter turnout and registration. We find that Medicaid increased voter turnout in the November 2008 Presidential election by about 7 percent overall, with the effects concentrated in men (18 percent increase) and in residents of Democratic counties (10 percent increase); there is suggestive evidence that the increase in voting reflected new voter registrations, rather than increased turnout among pre-existing registrants. There is no evidence of an increase in voter turnout in subsequent elections, up to and including the November 2010 midterm election.
期刊介绍：
In the last half-century, social scientists have engaged in a methodologically focused and substantively far-reaching mission to make the study of politics scientific. The mutually reinforcing components in this pursuit are the development of positive theories and the testing of their empirical implications. Although this paradigm has been associated with many advances in the understanding of politics, no leading journal of political science is dedicated primarily to the publication of positive political science.
