Undo revision 18346 by Closed Limelike Curves (talk) -- the word "decapitation" doesn't seem to show up in the Graham-Squire/McCune paper. It's not consistent with our editorial policy (EPOV) to introduce new jargon that isn't already in use elsewhere. It's also a gruesome term, and doesn't deserve introduction.

All these are examples of [[cardinal voting systems]], though some voters may be reluctant to have a compromise candidate tied with their favorite candidate on their respective ballots.
