- Title: The Ugly Face of Plurality with Runoff
- Abstract: The French presidential election, to be held April 23 (first round) and May 7 (second round) is the most crazy election that has taken place in the country since the beginning of the 5th Republic (1958). It is crazy not because of the situation inside or outside the country or anything important like that but simply because it makes use of plurality with runoff, which is (in my opinion) one of the most stupid and harmful voting rules. I will give a (fresh!) report on the election, from the early campaign to the final outcome, and I will illustrate the dysfunctions of the rule, and more specifically, I'll talk about manipulation of course, but also strategic candidacy, single-peakedness, and distortion.
