 Continuity: Suppose that a group of voters \(N_1\) elects a candidate \(A\) and a disjoint group of voters \(N_2\) elects a different candidate \(B\). Then there must be some number \(m\) such that the population consisting of the subgroup \(N_2\) together with \(m\) copies of \(N_1\) will elect \(A\).
