Note about Scantron paper ballots, use black pen! These are the ballots where you fill in the little circles and put the ballet into a machine and it counts the bubbles. I used to work with these for Michigan standardized testing in one of my jobs. This technology is why the bubbles must be filled in with a dark pencil or black pen.  Bring your own dark black pen to vote in case they hand you a blue marker.   Also remember that the poll workers are not highly trained, very detailed people. They don't understand the details of how these things work. They are simply told what to do by people who don't understand the details either. Your black pen will work. Make the circles dark, completely filled in, and stay within the lines or the ballot may get rejected when it is scanned by the machine. If your ballot is rejected there is a procedure to mark the old ballot as invalid, and you have the right to get a new ballot. Find a poll worker, tell them the ballot was rejected by the machine. The worker's first steps are they will try to get it to scan 2-3 times. If it doesn't scan after that they will give you a new ballot. Even if the ballot is slightly askew as it enters the machine, that will cause a bad scan.  The bars on the sides of the paper are critical too. They are used by the machine to align the ballot for scanning. You don't want any marker near them, and don't spill coffee or anything on them that might make a mark or wrinkle the paper.   Wrinkled or folder paper in critical areas may cause a rejected ballot as the paper may not scan those areas correctly.
