One of the most important rights of American citizens is the right to vote.This is why we were excited to launch Vote.USA.gov in September 2015, and why we are continuing our efforts to make it simple for Americans to register to vote. Thousands of sites link to USA.gov as the official source of government information and services. Beginning this week, Facebook is reminding its users of state voter registration deadlines and linking prominently to Vote.USA.gov to help users complete the registration process. Users can also share their registration status with friends and family, which can be a powerful tool in influencing others to register.
