State Senator J. Lowell Stoltzfus says he will not run for re-election in 2010. The Republican made the announcement at a dinner supporters attended in Salisbury. The 60-year-old Stoltzfus, who has represented the Lower Shore for 18 years, said he wants to spend more time with his wife, Sharon, who has Parkinson’s disease. He also wants to work on his nursery business. Stoltzfus was elected to the Senate’s District 38B seat in January 1992. He was the minority leader from September 2001 through December 2006.
