The voter registration deadline for Marion County voters is today. The Auditor’s Office in the Courthouse will be open from 8am-5pm today to allow residents to register to vote before the June 5th primary. Marion County Auditor Jake Grandia tells KNIA/KRLS News that same-day voter registration will still be available at polling sites on June 5th, but the preregistration process is simpler and less time-consuming.
