and to an abc news investigation. On the eve of this election. We learn of a powerful group, a million strong, heading out to those polling places, too. They're not getting in line to vote. They're there atch you. And one family is sounding the alarm. Here's abc's dan harris. Reporter: Teresa sharp, a grandmother in battleground ohio, says she's voted in every election since she was 18. Voting, to me, is, like, sacred. Reporter: So, imagine her surprise when she got this letter in the mail. You are hereby notified that your right to vote has been challenged by a qualified elector. Reporter: Six of her family members got similar letters. There's somebody out here trying to scare people into not voting. Reporter: So, who's behind this? A grassroots organization called true the vote. Willful fraudulent behavior. Reporter: The founder is catherine engelbrecht. Is your goal really to end voter fraud? Or is your goal really to intimidate voters who disagree with you politically? Our goal, really, is to encourage citizens to get involved in the process. Reporter: They are doing a community service, they say, by making sure there's no voter fraud. Right. Just the poor black neighborhoods, right? Everybody else is clean. Teresa sharp has nothing to worry about, because our citizens go into this race blind, party blind. Reporter: You are not in any way directly targeting these communities? Absolutely not. Reporter: True the vote is now vowing to mobilize a million poll watchers on election day to look out for fraud like people voting multiple times. In recent years, their activists have been accused of harassment in predominantly minority districts. Their founder insists true the vote the nonpartisan, although she herself runs a separate tea party group and has made very clear she would like to see president obama lose. And here is another twist. Study after study has actually found voter fraud to be virtually nonexistence. Virtually nonexistent. Another study in 2005 that showed that the federal government was charging more americans with violating migratory bird statutes than election fraud. What we've experienced suggests there's room for improvement. Reporter: As for teresa sharp, the county threw out the challenge against her and the other day, she voted early without incident. Meanwhile, true the vote now has poll watchers out at early voting places, including in minority neighborhoods, and the complaints have already begun.
