Query: Selecting Voting Locations for Fun and Profit   While manipulative attacks on elections have been well-studied, only recently
has attention turned to attacks that account for geographic information, which
are extremely common in the real world. The most well known in the media is
gerrymandering, in which district border-lines are changed to increase a
party's chance to win, but a different geographical manipulation involves
influencing the election by selecting the location of polling places, as many
people are not willing to go to any distance to vote. In this paper we initiate
the study of this manipulation. We find that while it is easy to manipulate the
selection of polling places on the line, it becomes difficult already on the
plane or in the case of more than two candidates. Moreover, we show that for
more than two candidates the problem is inapproximable. However, we find a few
restricted cases on the plane where some algorithms perform well. Finally, we
discuss how existing results for standard control actions hold in the
geographic setting, consider additional control actions in the geographic
setting, and suggest directions for future study.
