An interesting comparison between the different appeals of Karroubi and Mousavi (the whole piece is worth reading):
While Karroubi went for the liberal option of differentiating people into identity groups with different demands (women, students, intellectuals, ethnicities, religious minorities, etc), Musavi emphasized the universal demands of people’ who wanted to be heard and counted as political subjects. This subjectivity, emphasized by Musavi during his campaign and fully incarnated in the rallies of the past few days, is constituted by political intuition, creativity and recollection of the 79 revolution (no wonder that people so quickly reached an unexpected maturity, best manifested in the abstention from violence in their silent demonstrations).
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).
