<p>
Counterintuitively, we can prove that under reasonable assumptions Approval and Condorcet voting
actually are <i>not</i> in conflict
(<a href="http://www.rangevoting.org/AppCW.html">no-conflict theorem</a>) and it is plausible that approval voting
will actually be <i>more likely</i> in practice to elect honest-voter
Condorcet winners, than "official"
Condorcet methods!
</p>
<p>
And because strategic range voters generally vote approval-style, the same would
be true of <a href="http://www.rangevoting.org/RangeVoting.html">range voting</a> elections with strategic voters.
In other words:
</p><ul><li>
To the extent range voters are <i>strategic</i> they will elect
Condorcet winners (indeed quite likely doing so <i>better</i> than
"official" Condorcet methods);
</li><li>
whereas to the extent they are <i>honest</i>,
range voting should perform <a href="http://www.rangevoting.org/rangeVcond.html#slaves">better</a> than Condorcet.
</li></ul>
Even if you don't quite buy all that, we think you still will agree that
in practice, one should expect no great advantage for Condorcet methods over the
simpler range voting system.
