*so important*: if you’re voting by mail, assume the USPS will delay because it’s its policy. You can: —put it in drop box —go to counter to watch them postmark in front of you —if you’re dropping it in a mailbox, do it VERY EARLY.
Many states require that mail ballots be postmarked by a specific day. But due to a USPS rule announced late last year, voters may need to put their ballot in a mailbox days in advance.
