Do I need an ID to vote?
Only 34 states require you to bring some form of ID to vote. You can check out your state's requirements before heading to the polls. Here's a tip: It never hurts to over-prepare.
Can I bring a friend?
Actually, you can. Anyone with a disability, who might have trouble reading or writing or doesn't understand English well can bring someone with them to the polls.
Will I get in trouble if I take a photo of my ballot?
You may be tempted to post a photo on Instagram when you hit the voting booth, but selfies with your ballot could get you in trouble in some states. There are 18 states, including Florida, that don't allow photographs in polling places or voting booths or both. Read up on your state's law here.
