[Election-Methods] Do strategic voters stay home on election day?

[Steve Eppley]

Hi,

In elections where strategically-minded potential voters believe the 
odds are extremely low that their vote will be pivotal, do most of them 
conclude their best strategy is to not spend any time voting or even 
thinking about how to vote?

(In Australia voters are fined if they don't vote.  So, let's neglect 
Australia for this discussion.)
