• Under evaluative voting, the voter freely grades each candidate on a numerical scale, with the winning candidate being determined by the sum of the grades they receive. This paper compares evaluative voting with the two-round system, reporting on an experiment, conducted during the 2012 French presidential election, which attracted 2340 participants. Here we show that the two-round system favors �exclusive� candidates, that is candidates who elicit strong feelings, while evaluative rules favor �inclusive� candidates, that is candidates who attract the support of a large span of the electorate. These differences are explained by two complementary reasons: the opportunity for the voter to support several candidates under evaluative voting rules, and the specific pattern of strategic voting under the two-round voting rule.
