Popularity Boost

It's a proven fact that whoever stands up against Ayatollah Khamenei, will gain a major popularity boost. So I think the recent letter by the protesting MPs to the leader could also be seen in this way.

Because they have already said they plan to continue their efforts to reform the system, from outside the official power structre and from within the society and through different NGOs and if the allow them, through political parties. Therefore they'll need to regian people's trust and support before they are really sent out of the power in a few months.
