A bill to allow election-day voter registration in California was signed into law Monday by Governor Jerry Brown. The measure will not affect this year’s election; it will take effect on January 1, 2013 and will likely not be implemented until 2015, when a voter database known as Vote-Cal is expected to launch. Studies have found that same-day registration boosts voter turnout by an average of seven percentage points. “While other states try to restrict voters with new laws that burden the process, California allows voters to register online — and even on Election Day,” Brown said in a statement. California joins ten other states that have some form of election-day registration.
