Why should you vote?

[Francesca R]

Anyone think you should be able to auction off your vote?

No, it is self-limiting (and thus not "Kant style"). At some critical level of low turnout, the influence of one person increases enough to make it rational for them to vote. I don't know where the threshold is, but it's going to be before turnout shrinks to 1.

I can't think of an "n" for turnout that makes it rational to vote, where an "n+1" fails. Or even "n+10" or any number you pick. I am not understanding the significance of this proposed threshhold.

Can you provide an example?
