First, some voters only vote for a particular party because they fear being ruled by another. Suppose that other party emerges victorious from the election. In what sense do those voters consent to being ruled by the winners? Admittedly, the usual answer, that they consent because they took part in the election and therefore accepted that they might lose, may be true for some but it is not a universal psychological law. One might as well say that a person who defends himself against an attack, unsuccessfully as it turns out, thereby consented to being overwhelmed.
