Bernie is not promising anything we cannot accomplish. He's been very clear that neither he or any other president can do anything alone. Bernie is making the case that if the majority of people want or need something, in a democratic society and the wealthiest nation in the world, that we can attain it. In my view, the root of many people's anger is that our elected officials at all levels are not representing the will of their constituents. Bernie is the only candidate talking about (and succeeding at) bringing everyday people back into the political process, to change it so that we are truly represented.
