'''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. It is closely related to the class of [[:Category:Graded Bucklin methods|graded Bucklin systems]], in which equal and/or skipped rankings are allowed, which includes such systems as [[Majority Choice Approval]] (MCA) or [[Majority Judgment]]. Modern theorists tend to prefer graded Bucklin systems over ungraded ones, as they usually comply better with criteria such as [[FBC]].
== How did it work? ==
Line 86:
Fallback voting is equivalent to the [[Expanding Approvals Rule]] in the single-winner case under certain conditions.<blockquote>Remark 3 [...] For k = 1 and under linear orders for all but a subset of equally least preferred candidates applying the tweak in Remark 2 leads to the EAR [Expanding Approvals Rule] being equivalent to the Fallback voting rule (Brams and Sanver, 2009). <ref name="Aziz Lee 20172">{{cite web | last=Aziz | first=Haris | last2=Lee | first2=Barton | title=The Expanding Approvals Rule: Improving Proportional Representation and Monotonicity | website=arXiv.org | date=2017-08-25 | url=https://arxiv.org/abs/1708.07580v2 | access-date=2020-01-30|page=19}}</ref></blockquote>

There are a number of variations of Bucklin voting such as [[Iterated bucklin|Iterated Bucklin]], [[Expanding Approvals Rule]], [[Maximum Constrained Approval Bucklin]], [[Venzke Bucklin Variant]] and [[Majority Choice Approval|Majority Choice Approval/ER-Bucklin.]] [[Majority Judgment]] is a cardinal voting system which is similar.
