Iranian supporters of reformist presidential candidate Mir Hossein Mousavi take to the streets for electoral rallies in Tehran on June 8, 2009. "Bye, Bye Ahmadi!" cried young men and women, most of them dressed in green --Mousavi's campaign colour -- and carrying a thin green string as they formed a chain stretching the entire length of the 18-kilometre-long Valiasr Street. Even as Iran's presidential election has emerged as a straight fight between incumbent Mahmoud Ahmadinejad and former premier Mir Hossein Mousavi, there are two other candidates -- ex-parliament speaker Mehdi Karroubi and the ex-chief of Iran's powerful Revolutionary Guards Corps Mohsen Rezai -- in the race whose presence can define the outcome of the vote.
