Note: This enumeration is the same for the pre-election data and election results feed types. It isn't used with officeholder feeds.

The following table shows the enumerations for contest algorithms or rules in the Contest entity:

Value	Description
1-of-m	Each voter can select up to one option.
approval	Approval voting, where each voter can select as many options as desired.
borda	Borda count, where each voter can rank the options, and the rankings are assigned point values.
cumulative	Cumulative voting, where each voter can distribute their vote to up to N options.
majority	A 1-of-m method where the winner needs more than 50% of the vote to be elected.
n-of-m	A method where each voter can select up to N options.
plurality	A 1-of-m method where the option with the most votes is elected, regardless of whether the option has more than 50% of the vote.
proportional	A proportional representation method, which is any system that elects winners in proportion to the total vote. For the single transferable vote (STV) method, use rcv instead.
range	Range voting, where each voter can select a score for each option.
rcv	Ranked choice voting (RCV), where each voter can rank the options, and the ballots are counted in rounds. Also known as instant-runoff voting (IRV) and the single transferable vote (STV).
super-majority	A 1-of-m method where the winner needs more than some predetermined fraction of the vote to be elected, and where the fraction is more than 50%. For example, the winner might need three-fifths or two-thirds of the vote.
other	The vote variation is a type that isn't included in this enumeration. If used, provide the item's custom type in an OtherType element.
