I have no earthly idea.
I suppose it depends on how well organized they are, how violent the police reprisals are, if they can manage to make it last till the Olympics start kicking up, and of course if that dengue epidemic officials are predicting affects the protestors.
I've never been involved with this kind of protest, so it's really impossible for me to imagine all the factors that go into something like that.
What would be your guess?
