This in turn forced him to agree to acosta's mandate as he needs their support to get the constitution passed.

He doesn't need Acosta's support for that. The constitution goes to a national referendum in the fall. The people of Ecuador, not the assembly, will decide. Right now, it's looking more and more like it will be a referendum on Correa's leadership.

They're way behind in writing it BTW. I can't see how they'll get finished in time, so don't be surprised if they need an extension. I believe the mandate provides for 60 days. They're gonna need it, IMO.
