An interesting comparison between the different appeals of Karroubi and Mousavi (the whole piece is worth reading):
Musavi’s ‘people’ is also easily, but strongly, distinguished from Ahmadinejad’s anonymous masses dependent on state charity. Musavi’s people, as the collective appearing in the rallies, is made of religious women covered in chador walking hand in hand with westernized young women who are usually prosecuted for their appearance; veterans of war in wheelchairs next to young boys for whom the Iran-Iraq war is only an anecdote; and working class who have sacrificed their daily salary to participate in the rally next to the middle classes. This story is not limited to Tehran. Shiraz (two confirmed dead), Isfahan (one confirmed dead), Tabriz, Oroomiye are also part of this movement and other cities are joining with a predictable delay (as it was the case in 79 revolution).
