The deadline to register to vote in Ohio’s March 19th Primary Election is February 20th. Early in-person voting then will start February 21st. Voters must also update their voter registration if they have moved or if their name has changed. Voters who are unsure if they are registered can look it up on their Board of Elections website. Absentee ballots can be mailed to the voters until February 21st, but voters can fill out request forms now.
