During and after the Florida fiasco, I was a member of a Yahoo group that specialized in technical, mostly scientific, matters and wasn't political at all. One of the members, a professional statistician, made a very convincing case that any large election that comes out with a margin of victory less than about 1% is a tossup. There are a lot of uncertainties in even the best run election due to voter errors, equipment/counting errors and innocent mistakes on the part of election officials, leading to a margin of error of at least 1%. Attempts to make the margin of error smaller tend to make the process much more cumbersome. His conclusion was that any very close election could be decided by an honest. coin flip as well as by anything else.

Of course, the Florida election was decided in a less random and, in my opinion, not at all honest manner.
