Assume that voters must choose between voting yes (Y) and voting no (N
) on three propositions on a referendum. If the winning combination is
NYY on the first, second, and third propositions, respectively, the p
aradox of multiple elections is that NYY can receive the fewest votes
of the 2(3) = 8 combinations. Several variants of this paradox are ill
ustrated, and necessary and sufficient conditions for its occurrence,
related to the ''incoherence'' of support, are given. The paradox is s
hown, via an isomorphism, to be a generalization of the well-known par
adox of voting. One real-life example of the paradox involving voting
on propositions in California, in which not a single voter voted on th
e winning side of all the propositions, is given. Several empirical ex
amples of variants of the paradox that manifested themselves in federa
l elections - one of which led to divided government - and legislative
votes in the US House of Representatives, are also analyzed. Possible
normative implications of the paradox, such as allowing voters to vot
e directly for combinations using approval voting or the Borda count,
are discussed.
