Orzetto makes an interesting point. Ranked ballots make it easier to vote in a unique pattern, so voters can in effect "sign" their ballots, thus enabling vote selling or coersion if the ballots can be inspected by a "picciotto" (spy?)
There are some proposed voting integrity schemes (e.g. http://www.votegrity.com/) that would publish all the ballots on a website. In order to insure voter anonymity as much as possible, voters would have to be restricted to voting for just their top two or three choices. That would displease some voters who might like to vote for several alternative candidates before voting for a major party candidate.
Approval voting insures voter anonymity a lot better and easier than ranked ballot methods, partly because each candidate can be approved or disapproved on a separate ballot paper. Condorcet insures anonymity better than IRV because with Condorcet, a vote such as
Abe > Bill > Charlie
can be broken up into three separate ballot papers as
Abe > Bill
Abe > Charlie
Bill > Charlie
Condorcet can choose a winner using those pairwise preference votes, whereas IRV neeeds to see the whole string "Abe > Bill > Charlie".
Orzetto, was Condorcet really used in Italy, or was it IRV? That would be REALLY interesting if it was Condorcet, because I haven't heard of Condorcet being used in public elections before.
