In this article we employ the theory of power indices to evaluate the respective influence of the two classes of electors in the polling method introduced by the electoral law of 29 June 1820, a method know as the law of "double vote". After reviewing some of the main theoretical notions underlying the use of the Banzhaf index, we use simulations to evaluate the voting power of the two types of electors.
