When Increased Turnout Matters: Simulating the Partisan Impact of Full Turnout in Senate and Gubernatorial Elections

Abstract

What if everyone voted? There is consensus that increased turnout generally, but not always, benefits Democrats, but recent evidence suggests that it is unlikely to change election outcomes considering the paucity of close races. For the first time, we examine this question using gubernatorial races along with Senate races from 2008 and 2010, estimating the behavior of nonvoters based on individual‐level data from known voters. We find that the substantive effect of full turnout is understated, particularly in close gubernatorial races. As these races determine partisan control of executive branches, we demonstrate that full turnout would result in more politically meaningful changes than suggested in previous research focusing only on Senate or presidential elections. While the empirical consequences of increased turnout are well understood, our findings suggest that the substantive effects continue to be understated.Related Articles Stockemer, Daniel, and Stephanie Parent. 2014. “.” Politics & Policy 42 (): 221‐245. http://onlinelibrary.wiley.com/doi/10.1111/polp.12067/abstract Southwell, Priscilla. 2011. “.” Politics & Policy 39 (): 979‐996. http://onlinelibrary.wiley.com/doi/10.1111/j.1747-1346.2011.00330.x/abstract Stockemer, Daniel. 2013. “.” Politics & Policy 41 (): 189‐212. http://onlinelibrary.wiley.com/doi/10.1111/polp.12012/abstract
