@garthc Looking at that page, out of all votes in recorded history, almost none were decided by 1 vote and the vast majority of those were votes with only a few thousand to 15,000 voters total and as far as I can tell, none has occurred with say a million votes total.
Invidials votes in the vast majority of cases do not count - it's only if sufficient thousands or millions of people agree on the same thing in the same way that a vote works well.
