Since becoming law, the Affordable Care Act (ACA) has been used by political parties in attempts to mobilize voters. In a new study, Jake Haselswerdt, assistant professor of political science and public affairs at the University of Missouri, found a correlation between voter turnout and Medicaid expansion, a key component of the ACA. He says that increases in Medicaid enrollment are related to considerably higher voter turnout in states that expanded Medicaid. The effect is likely due to both an increase in turnout for new Medicaid beneficiaries and a backlash effect among constituents opposed to the law and its implementation.
