<p>I was going to type simply "Good question."<br>
<br>
One of the major justifications MJ has is that it (like Relevant
Ratings and IBIFA and Bucklin and Approval)<br>
meets the Favorite Betrayal Criterion (aka FBC) which isn't
compatible with Condorcet.<br>
<br>
In other words, MJ's (main) excuse for failing Condorcet is that
it meets FBC.<br>
</p>
<p>But when you add a 2-candidate runoff you always have a possible
Push-over incentive and so no<br>
compliance with FBC.<br>
<br>
And so the whole thing becomes a weird method that meets Condorcet
but probably fails Smith.<br>

<p>I know that i am just stuck in Condorcet land and I
haven't completely groked MJ (because i don't like the
ballot), but can you guys help me understand how **any**
candidate beats the Condorcet Winner in a runoff?</p>

<p>If you have an election method and subject that winner

method to the CW (whom must have been chosen from
ranked-ballot results) in a runoff, does not always the
CW win? If so, then why not just elect the CW?</p>

<div dir="auto">Indeed, that would be the case. But I think
voters may not realize the ramifications of their selections
in early use of any new method, so an option to reconsider
might be beneficial. </div>
