The other crucial fact is that the survey was done on May 11-20 and the election was on June 12. When they started the survey, former president Khatami was a candidate. He withdrew on May 17 in favor of Mir Hossein Musavi, who had just announced his candidacy. So during most of the period of the phone survey, Mousavi was not even a declared candidate. His "green wave," that inspired so much excitement among Iranian voters had not even been invented.
