Got my mail in ballot yesterday. Tempted to mail it but I'm a little skeptical on it ever reaching the Supervisor's office in time. I think I'll drop it at a ballot box as soon as early voting starts here.
I'd say just go for it if your state or county has a mail-in ballot tracker. You'll be able to see whether or not it gets to the supervisor's office in time, and if it doesn't or there is some issue with it (like a signature rejection or whatever), you can just vote in person.
How to track your mail-in ballot
According to a CNN review, 45 states and the District of Columbia allow you to track your ballot just like an Amazon package or food delivery.
