The two groups differed strongly over economic and foreign policy, with radicals tending to support mass political participation and state control of the economy, and oppose normalization of relations with the West. Conservatives used the power to disqualify candidates from running for office to deal with this problem. "The Council of Guardians disqualified nearly all radical candidates from the fall 1990 Assembly of Experts elections because they had failed to pass written and oral tests in Islamic jurisprudence." In the winter and spring of 1992 nearly one-third of the 3150 candidates for the 1992 election for the parliament were rejected, including 39 incumbents. Leading radicals such as Khalkhali, Nabvi, Bayat, and Hajjat al-Islam Hadi Ghaffari were sent packing because they lacked the "proper Islamic credentials."
