What happens if 14 is assigned to Bush, but the number 4 shows up on the printed ballot. Then you punch out 4, not 14. And when voting in person, remember that after the punch card is inserted into the slot, you don't see the numbers on the actual punch card. Nonetheless, you count down four holes from the top and punch that chad rather than the chad opposite the Bush name. How is that vote counted?
If 4 is assigned to a candidate, the software will register a vote for that candidate. If 4 is not assigned, the software will not count it at all since 4 is undefined. The software used may differ from what we had though. The stuff we had would not count anything for an undefined punch. It only recognized punches that corresponded to a defined, assigned position.
