PSA: You can call 866-OUR-VOTE from any state about any voting question or concern. If you are turned away for any reason, give them a call to double check your rights and ask for a provisional ballot at the polls - they have to give you one.
The number is 866-687-8683 or check out 866ourvote.org. The phone line offers multiple languages.
I see this is going around again. Still relevant in 2020!
