From the Argus Leader/Associated Press, it looks like the other petition scofflaw got probation as well:
Former South Dakota U.S. Senate candidate Clayton Walker has avoided jail time for election law violations, instead being sentenced Tuesday to two years of probation.
State Judge John Brown also ordered Walker to complete 200 hours of community service and told him to get a mental health evaluation within 30 days.
Walker declined comment after the sentencing, but previously said he believes the charges against him were politically motivated.
and….
Authorities indicted Walker in June 2014 for submitting nominating petitions that included names of dead people, fictitious people and Hollywood celebrities, and for falsely swearing that he witnessed signatures on his petitions. Authorities later accused him of making repeated phone calls to several state offices, harassing and threatening employees.
