The following is a statement from Jim Hall, former chairman of the National Transportation Safety Board, about his decision to leave the 11th state Senate District race: After reviewing my ongoing commitments and responsibilities I have decided not to be a candidate for the eleventh senatorial district in Tennessee. I currently have obligations to my business clients, my family and my community, as well as a personal interest in completing a book on the NTSB (National Transportation Safety Board). Knowing the demands of a campaign, I would have to set aside these obligations to make this race. After prayerful consideration I have decided I do not want to make that commitment at this time. I greatly appreciate all of those who have volunteered to support my campaign, to make contributions, and to vote for me. I hope you will remain active in the political process in Tennessee and exercise the obligation of free men and women to vote in the upcoming August and November elections. While this is not the appropriate time for me to run for office, I have been and will continue to be interested in state politics.
