Answer: Voting
Explanation: Voting is one of the most important and direct ways that citizens over the age of 18 can participate in politics. By voting, they can express their preferences and opinions on various issues and candidates, and influence the outcomes of elections. Voting is also a civic duty and a right that many people have fought for throughout history. In the United States, voting was not always a default right for all Americans. The Constitution did not specify who could vote, and many groups were excluded or discouraged from voting by various laws and practices. It took several amendments and acts to grant voting rights to black men, women, and young people over 18. Today, most American citizens over 18 are entitled to vote in federal and state elections, but some still face challenges such as voter suppression or lack of access to polling stations. Therefore, voting is not only a way to participate in politics, but also a way to protect and exercise one’s rights as a citizen.
