Declaration of Independence signed. Right to vote during the Colonial and Revolutionary periods is restricted to property owners - most of whom are white male Protestants over the age of 21. But, New Jersey's constitution of the same year enfranchised all adult inhabitants who owned a specified amount of property, including women.

The National Commission on Federal Election Reform recommends that all states allow felons to regain their right to vote after completing their criminal sentences.
Nearly four million US citizens cannot vote because of past felony convictions. In most states, felons are prohibited from voting while they are in prison or on parole.

The act established more efficient means for troops stationed overseas and expatriates to request and receive absentee ballots through the mail or electronically.
The Supreme Court weakens the law that had ensured federal government oversight of changes to voting systems in states with a history of discriminating against minority voters.
