Why and how does constitutional democracy in the united states depend on the active participation of its citizens?

 The correct answer is :  In the United States there is a representative democracy, which means that the government is chosen by the citizens. Officials vote for their government officials. These officials represent the ideas and concerns of citizens in government. Exercising the right to vote is a way of participating in democracy. Citizens can also contact an official when they want to support or modify a law. Voting in an election and contacting elected officials are two ways in which Americans can participate in their democracy.
