Abstract
In this paper we consider several ways in which voting systems can be manipulated and we pose some related ethical questions. Our focus is on the recent phenomenon of vote trading or vote swapping that was invented in 2000 and used in the 2000 and 2004 U.S. Presidential elections. Vote trading is an Internet-based technique that sought to allow Democrats in heavily Republican states (like Texas) to effectively vote in swing states (like Florida), where their votes would have more impact. We also look at some other new ways that voting systems can be manipulated and we consider the general question of whether there exist voting systems that cannot be manipulated.
