[3] Zambito was a Progressive Conservative Party of Quebec candidate in the 1985 provincial election, running in the Montreal division of Dorion.
The Progressive Conservatives did not have a strong provincial base in Quebec, and Zambito finished fourth against Liberal Violette Trépanier on election day.
In May 1988, Zambito and seven other councillors, led by Frank Zampino, charged that Renaud's administration was undemocratic and resigned from the party to sit as independents.
In 2003 Zambito was up for re-election in St-Leonard and joined newly formed political party Equipe Coderre after his former party Union Montreal, under the former Mayor Gerald Tremblay, applied for dissolution after several raids were conducted by Montreal's anti-corruption squad (UPAC) and an investigation by the Charbonneau Commission.
