Line 121:
Regular IRV eliminates B and elects A here, whereas Benham elects B for being the Condorcet winner ([[Pairwise beat|pairwise beats]] A and C 66 to 34 each). This is an example of an averted [[Center squeeze effect|center squeeze]] instance. Note that had B had a few more 1st choices, they would've had over 1/3rd of all 1st choice votes, and thus been guaranteed to win in IRV as well.
 
Because Benham's method is just IRV with the possibility of ending in an earlier round, it is possible to figure out who the Benham winner would be if given the full results of an IRV election (the round-by-round breakdown) and the pairwise comparison table for that election.
 
Like other Condorcet systems, Benham's method is vulnerable to [[tactical voting]] and generally ignores first place votes. This can lead to scenarios where fringe candidates that have not been scrutinized can win with only middle round votes. Benham's method also suffers from conflicting mechanisms, where first place votes are either ignored (once there is a condorcet winner) or are all that matters (for when there is not a condorcet winner).
It was invented by Chris Benham.
