We're back where we started: 15M didn't succeed because it tried to fight State with State. It's counterintuitive, but you can't vote politicians out voting some other politician in. Different dog, same collar. And if you become a politician yourself (and follow the system's rules in the process), you're fighting the State with State (which IMHO is pointless).
Also: you focus on politician's blame which I think is not the problem. I think it's not the person to be blamed, but the State. The institution itself.
