Here's a Condorcet IRV Hybrid similar to Benham's version:<br><br>Use IRV to eliminate candidates until one of the remaining candidates covers the other remaining candidates.<br><br>The rationale for this proposal is that a candidate who merely beats (pairwise) the other remaining candidates may not be considered strong enough for an exemption from elimination, but such a candidate has a stronger case if she also beats every candidate that is beaten by any of the remaining candidates.<br>
<br>What made me think of this version is that our DMC (Democratic Majority Choice) proposal to Toby Nixon eliminated low approval candidates until there was a beats all candidate among the remaining. In my opinion the DMC is much improved if you keep eliminating low approval candidates until one of the remaining candidates covers the others: you tend to get higher up the approval chain. In this modified version of DMC if there is no Condorcet candidate, then most of the time the highest approval Smith candidate will win. In particular, if (as in a cycle of three) no member of the Smith set covers any other member of the Smith set, then the highest Approval Smith candidate wins.<br>
<br>The following observation about Condorcet IRV Hybrids has probably already been made (but I have been gone for a while):<br><br>These hybrids have no good defense against burying. For example<br><br>Sincere ballots:<br>
<br>40 A>C<br>35 B>C<br>25 C>A<br><br>If the A faction decides to bury C, there is nothing the C faction can do about it unilaterally. They have to depend on the willingness of the B faction to elevate their compromise over favorite.<br>
