 Alperovich was elected to the Senate amid the political crisis of 2001, and ran for governor of Tucumán Province in 2003.Some commentators had speculated that Alperovich would not be able to become governor if elected because of the provincial law that required him to give an oath on the Christian Bible.A constitutional crisis ensued; ultimately, Alperovich's challenge to the provincia law met with success in the Supreme Court, which amended Tucumán's Constitution to allow Alperovich to take the oath on the Hebrew Torah.
