Line 6:
The mutual majority criterion is implied by the [[Smith criterion]].
Example for candidates A, B, C, D and E (scores are shown for each candidate, with the implicit ranked preferences in parentheses, and the unscored candidates assumed to be ranked last):<blockquote>17 A:10 B:9 C:8 (A>B>C >D=E)
17 B:10 C:9 A:8 (B>C>A >D=E)
18 C:10 A:9 B:8 (C>A>B >D=E)
49 D:10 E:10 (D>E >A=B=C)</blockquote>A, B, and C are preferred by a mutual majority, because a group of 52 voters (out of 100), an absolute majority, scored all of them higher than (preferred them over) all other candidates (D and E).
