US voting machines and other important votes

The video tutorial explains different voting methods, including optical scanners and e-voting machines. Optical scanners require voters to fill out paper ballots, which are then scanned. E-voting machines, or DREs, allow voters to make selections on a screen using a voter card. The tutorial also discusses absentee ballots, used by overseas voters, and provisional ballots, given to those with ID issues or at incorrect polling stations.
