BAKERSFIELD, Calif. (KGET) -- It's just six days until Election Day -- which is on Nov. 5 this year. There are some important reminders for voters as they cast their decisions in the final stretch. A friendly reminder that all registered voters should have three key pieces of mail -- a voter information guide from California's Secretary of State, as well as a sample ballot and official mail-in ballot from Kern Elections -- one per registered voter. "Voters should know there are many ways to turn in their ballots," said Kern Assistant Registrar of Voters Laura Cantu. "They can return vote-by-mail ballots at any of our drop boxes throughout Kern County, they can return their ballots here in our office … They can also return their ballot on election day at any poll site." Cantu added, "We have curbside ballot drop off here at our office this Saturday and Election Day." In California, each registered voter receives a vote-by-mail ballot. In Kern, there are 20 ballot drop box locations, including at the Bakersfield College and Cal State Bakersfield campuses. They're open 24 hours, 7 days a week until November 5. Drop boxes will close at 8 p.m. sharp Election Day. For those mailing back ballots, they must be postmarked by Nov. 5. "We accept postmarked [ballots] seven days after the election," noted Cantu. Voters must insert and seal their ballot into the enclosed return envelope. Election officials said voters should make sure their signatures on the vote-by-mail return envelope are accurate. "If the signature does not match, voters will receive a letter from us ... which is for nonmatches and unsigned returned vote by mail ballots ... fill it out, return it to our office," Cantu explained of the process. Cantu also emphasized ballots with invalid or missing signatures will not be counted. "Voters need to send the cure letters back to us two days prior to certification which is 26 days after the election," Cantu added. There's been a steady increase in county voter registration. According to Kern Elections, about 443,400 voters were registered to vote in May. By August, the number climbed to 447,300. By September, nearly 451,000 registered voters, and about 456,700 as of mid-October. The ratio of Democratic and Republican voters remains similar -- about 37% of Kern voters are Republican while about 34% are Democrats.
