A national voter fraud watchdog group announced Tuesday that it has uncovered at least 31 cases of absentee ballot fraud in New York and Florida -- a finding the group claims is "just the tip of the iceberg."
True the Vote, a group that focuses on voter fraud, said it turned over 31 cases to state and federal election authorities in which individuals cast their votes in two states in the same federal election -- which is a felony.
Logan Churchwell, a spokesman for the group, told FoxNews.com that the organization accessed Florida's complete voter registration roll and cross-referenced it against 10 percent of New York's list. It identified more than 1,700 people with voter registrations in both states. Of that number, 31 people allegedly voted in both states during the same federal election cycle.
Both Florida and New York require voters to cast ballots that correspond with their permanent home addresses. Under federal law, voters are prohibited from casting more than one ballot in the same election.
"This is further evidence of just how susceptible our election system is to voter fraud," the group's president, Catherine Engelbrecht, said in a statement.
The group said it has alerted the Office of Florida Secretary of State, the New York State Board of Elections and the U.S. Department of Justice of its finding.
"This should serve as a warning to any individual considering committing voter fraud in this year’s election," Engelbrecht said. "These findings are only the beginning of our effort. As today is National Voter Registration Day, it's important to remember that no candidate or cause is worth a felony conviction."
