It is physically impossible for a person to punch a stylus fully into the hole in the Vote-o-matic without breaking at least two of the four corners off a chad. Given that the instructions on the machine very clearly state that the stylus must be pushed all the way down, and includes a picture of the correct operation, and given that the strength required is not unreasonable, anyone who fails to do so cannot possibly be reasonably deemed to have voted.
While there may conceivably be some question regarding swinging chads, I think it very unlikely given the design of the machine that such things were an issue, at least on legitimately-cast ballots. At least on the cards I remember, if the card was inserted into the top of the machine, the chads would swing left or right (rather than vertically). There was nothing that could push them "swung shut"; instead they'd be removed by a scraper (if the stylus didn't remove them cleanly first).
The Democrats needed an excuse to bolux the 2000 election. That's the only reason for this whole fiasco. Not that any significant number of legitimately-cast votes were miscounted, but rather to promote FUD, while perhaps as a bonus also covering up evidence of fraud.
Bingo!! These machines were good enough to elect Davis, after all....
