This kind of thing pops up in all sorts of different areas in any large society. There are plenty of things that don't make much difference if a few people do them, but make all the difference if a lot of people do or don't. But in my area at least, votes do occasionally come down to a couple of dozen votes. I'm not in the US though and we don't really have gerrymandering, nor do we have anyone trying to disenfranchise on racial or class grounds - (in fact, here voting is compulsory!).
