[EM] Citation for immunity to strategic voting?

[Andrew Myers]

Hi all,

I'm writing a short paper on secure implementations of Condorcet voting.
I would like to claim that Condorcet methods are immune to strategic
voting when there is a Condorcet winner (that is, voters cannot improve
the election result from their perspective by voting insincerely). Is there
an appropriate paper to cite that makes this argument clearly? Thanks much,

-- Andrew
