Talk of potential fraud and the possibility of unofficial monitors appearing at the polls has left some Tennesseans wondering what to expect when they vote today.
But election officials say they're keeping watch on the watchers.
In Nashville, 172 people have been approved to be poll monitors — about as many as in past presidential races.
Davidson County election administrator Jeff Roberts says they should be easy to spot.
"They're credentialed. You can't just appoint yourself and walk in. You can come in to vote, and that's about it."
Observers are an assortment of people chosen by the parties, candidates and groups like the League of Women Voters and the NAACP.
They can roam about Davidson County's 160 precincts. But they don't have free range inside the polls.
"You know, you're not observing the voter actually voting," Roberts says. "You can observe the process and look for irregularities, but you can't interfere."
Voters who do suspect interference, fraud or any other irregularity can alert a poll official or call the Election Commission.
But Roberts says that, even at the end of an unprecedented campaign, he expects Election Day to run smoothly.
Polls are open until 7 tonight. You can find your polling location online by visiting the GoVoteTN website.
