It depends on active, informed citizens. The news media is mostly entertainment oriented. This means that all programming is seen as infotainment. Politics and policy is inherently complex. The political center and moderates are largely excluded from the popular culture events including television.
Talks shows almost never have three people in their interviews.
Yet most Americans actually vote moderate and prefer compromise and quiet, thoughtful discussion and problem solving. Politics and public service is largely reserved for adults, and often, older persons at that. Young people are generally overlooked and neglected by the candidates and parties. Politics and public service have been bashed and discredited. Students would prefer to get a business degree and manage a convenience store than serve in the legislature or Congress.
