  abstract =     {
        We introduce the notion of \emph{preliminary voting}, or \emph{pre-voting}, wherein
        a voter deposits---perhaps over the Internet---a \emph{preliminary vote} or \emph{prevote}
        with election authorities at some time before the close of elections.
        Prevotes are not official votes, and need not be kept private; indeed, election
        officials might, as a matter of announced policy, publish the list of
        received prevotes together with the names of the voters submitting such
        prevotes. With prevoting, a voter must visit a polling site to make any
        final adjustments to his prevote in private, and to actually cast her (perhaps
        modified) prevote.                  
                 },
