The demonstrations are getting larger, and the calls for the military to step down now - not next year - louder. Tuesday's crowd is the biggest to mass in Tahrir Square since the unrest began four days ago. Men, women, young and old, are united in their demand that civilian rule begin now. "As you can see, not just one type of Egyptian here. All the Egyptian here: Islamic, liberal or communist. Everyone is here. Egyptian and Muslims and Christians. Everyone is here," one protester said. Some believe the momentum of the unrest, sparked by a proposal that the military rulers prolong their political influence, will speak for itself.
