Daryush, an Iranian Christian whose name has been changed to protect his identity, told California-based Open Doors USA that the majority of people he spoke to "consider the elections a fraud and don't accept the results at all."
Even many people in Shahe Cheragh, a predominantly religious and conservative district of the southwest city of Shiraz, voted for reformist and more liberal candidate Mirhossein Mousavi.
Daryush says many people, Muslims and Christians alike, have been turned off by the election results, accusing it of being rigged and vowing to never participate in an election again because "it was a total fraud."
Besides Daryush, Open Doors probed deeper and asked 28 other Christians from Tehran, Shiraz and Isfahan, all of whom said they voted for Mousavi, who had promised more religious freedom during his campaign.
Since the announcement of the results, the streets of Tehran and elsewhere have been filled with pro-Mousavi demonstrators. On Tuesday, thousands of pro-reform protesters marched for the second straight day in the Iranian capital. A day earlier, hundreds of thousands of Mousavi supporters had demonstrated in the central streets of Tehran.
Mousavi himself has proclaimed he won the presidential election and is demanding that the government annul Ahmadinejad's victory and organize a new election.
On Monday, Supreme Leader Ayatollah Ali Khamenei, who is more influential than the Iranian president, said the government will investigate the election. However, his announcement failed to assure Mousavi supporters, who engaged in a massive rally afterwards.
In districts in Shiraz, young people are reportedly being arrested and beaten for denouncing Ahmadinejad's victory.
"A friend who lives near the university and student dorms told me she heard screaming, shouting and gunfire in the early hours of the morning," Daryush said. "The predominately young demonstrators are calling Ahmadinejad a dictator and yell chants like 'Ma dolate zoor nemikhaim' meaning 'we don't want a government of force.'"
"They also yell at the security forces and call them traitors and vote stealers," the Iranian source reports. "A friend said that within the security forces are pro-Mousavi followers, saying 'beechareh shodim!' or 'we are without hope.'"
Some Iranians had considered Iran to be a "limited" democracy before the election, Daryush said. Although all the candidates were hand picked by the regime, some Iranians felt they could at least choose among them, the Iranian Christian explained.
But this election now has some Iranians lamenting that there is "no democracy at all…we have an Islamic dictatorship."
In the United States, President Obama has expressed concern about the election results but has refrained from making any strong statements about it being a fraud. He said Tuesday that "it's not productive, given the history of U.S.-Iranian relations" for the U.S. "to be seen as meddling" in Iranian affairs.
The U.S. and Iran has had no diplomatic relations for 30 years.
Obama voiced hope, however, that dissatisfied Iranians will help their country become more open to debate and democracy.
"We need to continue to pray for the situation in Iran, especially for the Christians caught in the crossfire," says Open Doors USA president and CEO Carl Moeller. "This could be a pivotal point in the history of Iran and the future of believers who live there."
