Iran's reformists are hoping a high turnout in the upcoming presidential election would help them oust hard-line President Mahmoud Ahmadinejad, who they say pushed the country deeper into international isolation and economic trouble.
The outcome of the June 12 vote may decide the direction Iran will take, both in the offer of dialogue from the Obama administration and in the confrontation with the West over its nuclear activities.
Iranian reformists, who seek better relations with the West and easing of social and political restrictions at home, have criticized Amadinejad for focusing too much on dueling with the US and Israel, rather then dealing with the faltering economy.
Campaigning officially kicked off Friday, with only 20 days left to entice the 46.2 million eligible Iranian voters to the polls. Reformists' posters across Teheran warn that a low turnout could bring the hardline president another term in office.
