"Those disaffected by the presidents confrontational tactics have turned to Rafsanjani, whose backers now reportedly include Iranian Supreme Leader Ayatollah Ali Khamenei"
If Khamenei were truly becoming a backer of Rafsanjani rather than Ahmadinejad, they'd get rid of Ahmadinejad.
I think you're correct but I think things are really complicated...with Mesbah Yazdi (Ahmadinejad's favorite Ayatollah) lobbying hard to replace Khamenei as Supreme Leader.
And remember that military plane crash last month(?) that had many Khamenei loyalist (senior IRGC officers) on board (and now dead).
My small brain aches trying to sort all this stuff out. I must be a masochist, because I thoroughly enjoy it.
