The only way to dimple that many ballots is by stacking them and poking “new” votes.
The whole idea is to do a stack at a time. These are cards that have already been punched (actual votes). The result of a large stack can be hanging chads on some ballots in the middle of the stack and dimples on the bottom of the stack. Dimples to a DemocRAT means voter intent.
By pushing the wire through your guys punch one of 3 things happen.
1) If there are no votes for any candidate it becomes a vote for your guy.
2) A vote for your guy is unchanged as the wire passes throught the hole.
3) It invalidates a ballot for any other candidate for the office because it becomes a double punch.
The only way to fix this punch card tampering is to use electronic voting machines that use software that allows only a set number of votes for each office (President and Congress is 1). You shouldn’t have any double punch issues.
