Conservatives in Iran are worried that they have too many horses in the 17 June presidential race. Of the eight candidates, four are firmly in the hard-line camp and are referred to as "principlists" (osulgarayan) -- Tehran Mayor Mahmud Ahmadinejad, former state broadcasting chief Ali Larijani, former police chief Mohammad Baqer Qalibaf, and Expediency Council Secretary Mohsen Rezai. Another candidate, Expediency Council Chairman and two-term president (1989-97) Ayatollah Ali-Akbar Hashemi-Rafsanjani, can be considered a center-right candidate, but he is insufficiently conservative for most hard-line activists.
