TEHRAN, Iran (AP) — It’s not just young, liberal rich kids anymore: Whole families, taxi drivers, even conservative women in black chadors are joining Iran’s opposition street protests. They say they want something simple: their votes counted and their voices heard. What they will settle for — or push for — is a far bigger question. It’s still too early to determine if the street protests will morph into a solid political opposition movement led by President Mahmoud Ahmadinejad’s top opponent, Mir Hossein Mousavi. And some Iranians have expressed doubt about people’s willingness to sustain the momentum. But in Tehran and other cities throughout the country, Mousavi supporters — from both the upper- and middle-classes — are sending a strong message.
