As hopes for Rafsanjani's meddling & talking sense to Khamenei fade: Karoubi and Mousavi strike out again.

Today:

Ahmadinejad, who was supposed to appear in Tehran University has chickened out. (see video below and more here)
Mousavi, who is accused of Mujahedin-like treason, has issued another statement (#13) that he is not backing off!
And Karoubi has written another public letter to Hashemi Rafsanjani, scolding him for his poor (and cowardly) performance as the head of Assembly of experts.
