Bucklin is a [[voting system]] that can be used for single-member districts and also multi-member districts. It is also known as the Grand Junction system after Grand Junction, Colorado, where it was first proposed.
does it work? ==
are allowed [[Preferential_voting|rank preference ballots]] - first, second, third.
First choice votes
are first counted. If one candidate has a majority, that candidate wins. Otherwise the second choices are added to the first choices. Again, if a candidate with a majority vote is found, the winner is the candidate with the most votes in that round. Lower rankings are added as needed.
is defined as half the number of voters, similar to [[absolute majority]]. Since after the first round there are more votes cast than voters, it is possible more than one candidate to have majority support.
For multi-member districts, voters
mark as many first choices as there are seats to be filled. Voters mark the same number of second and further choices. In some localities, the voter was required to mark a full set of first choices for his or her ballot to be valid.
is it used? ==
This method was apparently first used in Geneva during the French Revolution, in the period from 1792 to 1798, at the suggestion of the Marquis de Condorcet. This was a time of upheaval and experiment, and this usage has only recently come to light again.
Voters supporting a strong candidate have a advantage to "Bullet Vote" (Only offer one ranking), in hopes that other voters will add enough votes to help their candidate win. This strategy is most secure if the supported candidate appears likely to gain many second rank votes.
In the above example, Memphis voters have the most first place votes and might not offer a second preference in hopes of winning, but
it fails because they are not a second favorite from competitors.
