A proposal that would require California to verify proof of citizenship when a person registers to vote and require voters to provide identification at polling places will be included on the November ballot. The proposal is being supported by Republicans and aims to strengthen confidence in voting in California, where there are over 23 million registered voters. Other provisions would require those voting through popular mail-in ballots to provide the last four digits of a government-issued ID, such as a Social Security number. Critics argue that such requirements make it more difficult for people to vote, particularly those with disabilities, and those without driver’s licenses.
