Isaac-Sibille was elected to the National Assembly in 1988 to represent Rhône's 1st constituency, defeating the Socialist Party's Gérard Collomb.[4] She was re-elected in 1993 with 70.65% of the vote. She defeated Collomb again in 1997. In 2002, Anne-Marie Comparini was chosen to represent the Union for French Democracy.[5] Therefore, Isaac-Sibille represented the Miscellaneous right, but only received 12.10% of the vote in the first round.[6] She refused to support Comparini, citing a "betrayal" in 1999.[7]
In 2003, Isaac-Sibille became a member of the Commission de surveillance et de contrôle des publications destinées à l'enfance et à l'adolescence. She also served as president of the association for the Médaille de la Famille française.[citation needed]
