Check your voter registration status. Lots of states have been doing purges and you may not have gotten the notification in the mail!
If you’re not registered where you think you should be: Register to vote!
One of my students whose wife is a librarian gave me a tip– your local public library may have postage-paid voter registration forms and a mailbox to drop them in if you’re in one of the states that doesn’t allow online registration.
Let me know if you have any questions or tips in the comments!
