But let me introduce you to Hanging Chad. https://en.wikipedia.org/wiki/Chad_(paper) https://en.wikipedia.org/wiki/Chad_(paper) https://en.wikipedia.org/wiki/Florida_election_recount https://en.wikipedia.org/wiki/Florida_election_recount Although, calling this system a "Paper ballot" is not quite the truth. While it uses paper as the medium, the hole punching method is non-traditional in relation to basic written checks/X's or even scantron selection (which also has issues). But my point is that even "simple" and "low tech" methods can still have unexpected issues, such as the infamous Florida case.
