It sounds to me that the disatisfaction comes from different perspective on how to tackle an issue.
For example, I could be dissatisfied by all the benefits CA are doing, i dont think they tackle much of the root problem or that it ends up with more fraud than help, but it has been working for a long time and I believe the same dish cant please all tongues.
That's why voting is so important and the integrity of it is so important.

If there has been any fraud or cheater, whether or not it change the result, it is unacceptable. It's like a dangerous driver could get a ticket without having actually caused an accident on the road.
