The folks at Pennsylvania Ave. don't need to hear more from U.S. citizens or from more of U.S. citizens in order for needed change to happen. We can't make them care. Our society is trapped by some kind of pathological belief that we can and should change politicians, and that is accompanied by a co-dependent slave mentality that makes us fear challenging the status quo.
This combination glorifies bullies and gang wars, which are politely described in terms of identity politics. It encourages everyone to micro manage each other based on standards dictated to us by corporations (mainly the psychiatric industry which coordinates efforts with our judicial system) and be disgusted by the diversity we're taught is a weakness while apathetically awaiting a miraculous savior to grace the oval office.
The method of operation in our current government is such that the corporations in command of our political system have a responsibility to their stock holders to oppose caring when it interferes with profits.
The people who care are the people who can change things, and they don't have those financial and political limitations. They are the ones that need to hear our voice and the disenfranchised need to be empowered with something as old-fashioned and trite as kindness at every opportunity. That kind of change doesn't come from Washington.
If you don't see how you've been held hostage, pimped out, or otherwise exploited by the Democratic party based on Republicans being worse then you are either part of the problem, or you aren't paying close attention.
Change happens in the minds and hearts of people. When people are empowered to think they change what they believe, how they feel, and ultimately how they act. When enough of that happens the government will have no choice but listen but until then they have nothing to listen to.
