When we don't pay close attention to the decisions made by our leaders, when we fail to educate ourselves about the major issues of the day, when we choose not to make our voices and opinions heard, that's when democracy breaks down. That's when power is abused. That's when the most extreme voices in our society fill the void that we leave. That's when powerful interests and their lobbyists are most able to buy access and influence in the corridors of power - because none of us are there to speak up and stop them.
