What part of TN do you live in?
If you are not allowed to drive to the polling place, and can't walk there, call your local RP HQ and I guarantee that they will get someone to drive you to your poll!I live in Collierville. I have my voter registration card but still have my out of state driver license.
You're good to go godawgs. I live out in Lakeland, and when I went in for early registration, they didn't even try to look at my license. All you need is the voter registration card.
Hell, I even brought some mail with my address on it because my license still has my old address on it, but it didn't matter. They just took my registration card, gave me one of those diebold voter cards and let me at it.
