I would HIGHLY recommend bringing two forms of ID [a gov. i.e. your license or photo ID AND your voter ID] with you to poll. Some states have voter ID laws, and in other states you need your ID if it’s your first time voting at that particular location.
Avoid any trouble, don’t wear any pins, tshirts, etc. for a particular candidates. Some areas consider it passive electioneering.
You CAN NOT vote via text, online, etc. Anyone advertising otherwise is lying.
The only person to ask you for your ID should be the individual working the polls sitting at a table inside the building in question. If anyone else asks you for your ID or gives you a hard time, they have no authority to do so and should be avoided.
You CAN NOT take a photo of your ballot/voting machine/etc. Take a cute photo with your “I Voted” sticker after and call it a day.
Most importantly, stay safe, be smart and VOTE VOTE VOTE
