In a constitutional democracy, citizens play a crucial role by participating in elections, advocating for issues, and holding leaders accountable. Their engagement ensures that representatives act in the public's interest and reflect the diverse voices within society. Citizens also contribute to the democratic process by exercising their rights to free speech, assembly, and petitioning the government. Through civic education and active participation, individuals can influence policies and promote social change. Ultimately, a healthy democracy relies on informed and engaged citizens to uphold democratic principles and foster a just society.
