Suppose Q1 < Q2. Then candidate B must be elected with zero probability. Criterion 2: Suppose Q1 is the number of voters who strictly prefer candidate B to at least one candidate. Suppose Q2 is the number of voters who strictly prefer candidate A to candidate B. Suppose Q1 < Q2. Then candidate B must be elected with zero probability.
