The referendum was carried with an overwhelming majority, with nearly 98% in favour of convening the assembly. 116 lists or candidates ran for 70 seats in the constitutional assembly. The Liberal Party alone accounted for 49 of these lists, having decided to run several separate lists - unlike the other parties - to take advantage of electoral rules. Voters cast their votes for a single/list candidate, with the seats then attributed using the electoral quotient and largest remainders. The single most popular list was that of the AD M-19, led by Antonio Navarro Wolff, which won 992,613 votes and 19 seats.
