Dear Donald,

I couldn't find that quotation of Robert Winters that you were
mentioning in one of your last mails. Could you -please- tell me
where to find Rob Winters' quotation? I have only found the
following quotations:

Robert Winters wrote (5 Sep 1998):
> Let's not overstate the negatives of Droop vs. Hare in such absolute
> terms. Cambridge uses the Droop Quota in electing 9 councillors. In 1991,
> over 80% of voters had their top choice elected, about 95% had their
> first or second choice elected, and about 97% had one of their top three
> choices elected. I have not done the calculations on the 1997 election

> the blanket statement that "10% of the votes were wasted."

> Your assertion that "only candidates of the top three parties are to be
> elected" shows at least some misunderstanding of STV. The beauty of STV
> is that that every individual voter may choose his own criteria for
> selecting and ranking candidates. I can assure you that the Cambridge
