The document discusses the expansion of voting rights in the United States over time. Initially, only white property-owning men could vote, but several amendments granted voting rights to African Americans, women, and 18-year-olds. Voter turnout in the US is lower than in European democracies due to factors like registration requirements and the frequency of elections. The document also examines different forms of political participation beyond voting, such as social movements, protests, and virtual participation, noting that Americans are less likely to protest than citizens in other countries.
