The Declaration of Independence was signed August 2, 1776. But THAT was only the beginning of the revolution which has gone on for over two centuries.
The founders of the United States built into the election system the means for a perpetual refreshing of government. Voters can unite to remove unwanted leaders from office. Voters can unite to place whomever they wish in the seats of government.
Every leader is bound by the constitutions, bylaws, and articles of government that grants them the very right to serve. Every voter is empowered by the same.
The American Revolution is an on-going process. Battles are won in the voting booths and on the ballets. Bombs and bullets are not needed; only resolute people willing to voice their ideas and offer their support to candidates who share their views.
When a majority of voters agree, then their will is done. The elected officials are, by design, there to see that their views are represented.
Revolution in the U.S. is built into the election system. Each election is the opportunity to affirm or disavow the work of the elected. Each election offers the chance to make changes.
Your VOTE is your instrument of governmental change.
