Fortunately, we don't actually need to hold an election . the borda count lists position numbers next to names in a preference schedule. Such an estimator can be more reliable than any of its individual components. If this property is absent if Veronica gives correlated rankings to candidates with shared attributes then the maximum likelihood property is lost, and the Borda count is subject to nomination effects: a candidate is more likely to be elected if there are similar candidates on the ballot. Borda Count Vote Calculator Instructions Complete the Preference Summary with up to 10 candidate options and up to 10 ballot variations.
