What do low voter turnout and political apathy endanger?

These endanger democracy. If people do not participate (if they do not pay attention to the issues and they do not vote), only a small number of vested interests will control the government. Democracy works best when a large number of people let their opinions be known; some people express themselves by volunteering to help in a campaign, or by attending meetings to learn more about the candidates. When citizens vote, they are choosing the candidates they believe will most closely represent their views. Thus, low voter turnout means the public was not engaged and/or did not feel excited about any of the candidates.
