We have analyzed the likely impact on voter turnout should California adopt Election Day Registration (EDR). The availability of EDR procedures should give voters who have not previously registered or need to update their information the opportunity to vote. Consistent with existing research on the impact of Election Day Registration in the other states that use this process, we find that EDR would likely lead to substantial increases in voter turnout. We offer the following voter turnout estimates for California under EDR:

-- Overall turnout could go up by 4.8 percent

-- Turnout among those aged 18 to 25 could increase by 9.0 percent

-- Turnout for those who have moved in the last six months could increase by 7.3 percent

-- Turnout for Latinos and newly-naturalized citizens could each rise by 5.1 percent
