(Preble County, OH)--Preble County Commissioner Rachael Vonderhaar, who is on the primary ballot, is firing back after an opponent challenged her record of attendance.  Information sent to multiple media outlets indicated that Vonderhaar has missed 44 commissioners meetings in the last three years.  She responded Thursday by indicating that she was battling a serious health issue during that time, but still attended 84% of the meetings.  Preble County commissioners meet about a hundred times each year.  She attended 235 of 279 meetings over the three years in question.
