Dozens of counties across the US have been put on notice after a finding by the Public Interest Legal Foundation (PILF) that indicates they have more registered voters on the book than eligible residents living in those counties.

Michigan is the worst offender.

PILF has sent letters to 141 counties in 21 states indicating that housekeeping needs to be done to ensure that only living, eligible voters are registered. The next step is to bring lawsuits against counties that don't comply, under the National Voter Registration Act.

Michigan has 24 counties in violation of the NVRA. Kentucky (18), Illinois (17), Indiana (11), and Alabama (10) round out the top five. The complete list is found here.

“Corrupted voter rolls provide the perfect environment for voter fraud,” said J. Christian Adams, President and General Counsel of PILF.  “Close elections tainted by voter fraud turned control of the United States Senate in 2009.  Too much is at stake in 2016 to allow that to happen again.”
