Secretary of State Tre Hargett is urging Tennesseans to use #GoVoteTN on social media as a way to encourage others to register to vote.  September is National Voter Registration Month. He is encouraging those voters to make a sign saying “I’m registered to vote. Are you?” and to post them on the site. #GoVoteTN is consistently one of the most successful state-led voter registration social media campaigns in the country. Voters must be registered at least 30 days before an election to cast a ballot. Tuesday, October 11 is the registration deadline to vote in the November 8 general election.
