[EM] Bucklin PR ?

[Chris Benham]

In  November 2005,  I suggested  a PR version of  ER-Bucklin (whole).
It  has been pointed out to me that one word is wrong. In step 2, 
"amount"  should instead  be "proportion".

The corrected version:
"Voters rank candidates, truncatation and equal-ranking ok.

The winning threshold  to elect the first winner is a Droop quota 
(number of valid ballots/number of seats +1).

(1) Commence the ER-Bucklin(whole) process until the candidate with the 
highest score has a winning threshold.That single candidate is elected.

(2) Reduce the weight of all the ballots that contributed to the 
winner's tally by an equal proportion which sums to a Droop quota.
(Then delete the winner from the ballots.)

(3) Based on these reweighted ballots, the reduced number of unfilled 
seats, and not counting as valid any now exhausted ballots,reset the Droop quota.

(4) Repeat  the above three steps until all the seats are filled."
