MINNEAPOLIS (WCCO/AP) –An elderly St. Peter, Minn. woman diagnosed with Parkinson’s disease and dementia has been charged with voter fraud.

Margaret Schneider, 86, says she forgot she had voted by absentee ballot in the 2012 primary election and about a month later, on Aug. 14, the great-great-grandmother went to her polling place to vote.

Now Schneider finds herself facing a felony charge, and a court appearance April 2. She faces up to five years in prison. Not only will she fight the charge, she will not use an attorney. She says she did not do anything wrong.

WCCO talked to legal experts who say Schneider has an excellence defense. The law requires intent, and she can argue she simply forgot and didn’t intend to vote twice.
