________is the single-most important political act for most Americans.

A) Peaceful protest
B) Writing a letter to the editor
C) Contributing to political campaigns
D) Voting

Voting is the cornerstone of democracy and the most direct way for Americans to participate in the political process. It allows individuals to have a say in determining who represents them at various levels of government and to express their preferences on important issues. While peaceful protest, letters to the editor, and political contributions can all be important forms of political expression, none have the same impact as voting in shaping the outcome of elections and influencing public policy.
