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.
