Campaign finance reform is a necessary step to fixing our broken and almost non-functional democracy. The reality is corporations have been enabled by the government to make money into speech, and have used this to further their takeover of the United States. If donors want to have their voices heard, they are going to have to join the movement against this.
Campaign finance reform only serves to place limits on the amount of influence any particular entity can have in a given election. Instead of silencing any voices, we should encourage as many voices as possible so that as a country we can choose what seems the best to us from this multitude of policy positions. Limits on campaign finance stifle many such voices and positions.
