Democratic lawmakers say allowing voters to register and cast ballots on the same day would increase election participation, but some county officials worry that it would further complicate the voting process.
States with same-day registration have turnout rates nearly 6 percent higher than states that don’t offer it, according to Demos, a progressive public policy research group.
Demos counsel Liz Kennedy said 640,000 Americans voted nationally under same-day registration laws in the 2010 general election. The group’s preliminary research for the 2012 general election, which doesn’t yet include data from all jurisdictions with same-day registration, suggests that more than 800,000 people voted under the laws.
