LAUSR

We estimate effects of early voting on voter turnout using a 2010 homogenization law from Ohio that forced some counties to expand and others to contract early voting. Using voter registration data, we compare individuals who live within the same 2x2 mile squareblock but in different counties. We find substantial positive impacts of early voting on turnout equal to 0.22 percentage points of additional turnout per additional early voting day. We also find greater impacts on women, Democrats, independents, and those of child-bearing and working age. We simulate impacts of national early day laws on recent election outcomes.
