Political participation refers to activities citizens engage in to influence government actions or policymaking, either directly or indirectly. This can include voting, contacting officials, campaign volunteering, protesting, or running for office. According to studies, most common forms of participation in the US include watching campaigns on TV, voting, and trying to influence others' votes. Over time, voting rights have expanded from only white, male landowners to include all races, both sexes, and younger citizens due to abolition, women's suffrage, and civil rights movements challenging discriminatory policies. Today, states have little power to restrict suffrage.
