As a country, America is defined by the ideas of this being a democratic nation. A democracy refers to a country in which individuals choose what happens in the government. In this case, America represents these democratic ideals because our citizens have the opportunity to pick who runs our local, state, and national government.
With this in mind, it is the responsibility of American citizens to use their power of the vote in order to put in place the individuals who they think will help the country the most.
