There is also an incentive not to vote (or more accurately, a lack of incentive to vote) for many people, simply because they don't believe that their vote matters enough to be worth the effort. It's a combination of the unlikelihood of their vote mattering, the lack of value even in the unlikely event that their vote does matter (since your choice is between a douche and a turd sandwich), against the costs of voting. For some people the vote is worth it, for others it is not. Undoubtedly, voting becomes more valuable as votes become fewer, so low numbers should be more enticing to voters, and there's an equilibrium of sorts. But as we're seeing, that equilibrium is getting lower all the time.
