Voting can be done as an act of altruism (in addition to other reasons), buying a small chance of very large impact, for which it can easily have a positive expected value.
I agree with this argument, but note that it only applies if you actually believe that the differences between the policies that Obama and Romney are likely to implement do amount to a very large overall utility differential (and that you can know beforehand in which direction it goes). I suspect that Konkvistador does not share this premise.
Large enough to be millions of times what you would buy with a $50 charitable donation. That's not a terribly high bar for differences between candidates. And certainly one's vote is more influential in primary elections than general elections, and in swing states, and in lower turnout regions, etc. Policy differences can also be clearer in other races and cases, e.g. voting on single initiatives in California.
Don't let your minds be killed, but I was wondering if there were any existential risk angles to the coming American election (if there isn't, then I'll simply retreat to raw, enjoyable and empty tribalism).
I can see three (quite tenuous) angles:
But these all seem weak factors. So, less wronger, let me know: are the things I should care about in the election, or can I just lie back and enjoy it as a piece of interesting theatre?
