RT Journal Article SR Electronic T1 The Full Impact of the Affordable Care Act on Political Participation JF RSF: The Russell Sage Foundation Journal of the Social Sciences FD Russell Sage Foundation SP 179 OP 204 DO 10.7758/RSF.2020.6.2.08 VO 6 IS 2 A1 Charles Courtemanche A1 James Marton A1 Aaron Yelowitz YR 2020 UL http://www.rsfjournal.org/content/6/2/179.abstract AB This article examines the impact of both the Medicaid expansion and the private insurance-related components of the Affordable Care Act (ACA) on voter turnout and registration. We employ a difference-in-difference-in-differences identification strategy exploiting variation over time, state Medicaid expansion status, and within-state local area pre-ACA uninsured rates. Using data between 2006 and 2016 from the November Current Population Survey and the Census Bureau’s Small Area Health Insurance Estimates, our results suggest little effect of the ACA on voter turnout or registration.
