Democracy requires a lot from politicians. It requires them to get and stay elected by maintaining a favorable rating over their competition for the job. We, the people have demonstrated time and time again that part of doing that can be bought by media exposure. Raising money to do that has to be by courting special interests, but not at the expense of constituent satisfaction.
We all have "special interests" defined by the needs of a minority, as well as "general interests" defined by the needs of the majority.
We all have short term vs long term interests.
We, as a country live in a global environment, influenceable, but not controllable by us.
Part of our global environment is technological, producing somewhat at random, capability to do great good for humanity, and great harm.
We are diverse in race, religion, wealth, morality, geographically, by gender, and by age.
It's a wonder that anything gets done right given the complexity.
But, in the final analysis, we have government of, by, and for we, the people.
Of.
By.
For.
It is our creation and responsibility.
We are free to the degree that we choose to be by our democratic actions.
We can be enslaved but only to the degree that we surrender democracy to special interests.
