> We can have assumptions/expectations about the likely outcomes, some of which would statistically make individual votes "insignificant," but those assumptions may or may not be true (see: this year, duh); therefore every vote is made on the tacit recognition that it MAY matter.

We have hundreds of years of Presidential elections to show that individual votes are insignificant. That's a lot of empirical evidence. And given the size of the electorate, the probability of a one vote margin is statistically extremely unlikely.

What is "matter" supposed to mean, exactly?

Let's say there's a ballot counting error, and the announced results are mistaken. Does that matter? I would say no, that doesn't matter, as long as the outcome of the election wouldn't change on a recount of ballots. This is why, by law, they don't do a recount unless the margin is extremely small. Because otherwise, it doesn't matter. The exact vote total is only of marginal interest; in a sense, it's trivial.
