Dennis Callahan, a former mayor of Annapolis and the current director of Anne Arundel County's recreation and parks department, announced his Democratic candidacy for county executive before about 100 supporters yesterday at Crofton Country Club.
Callahan, 64, had planned to make his announcement in the spring but said he moved up the date based on the fundraising efforts of Sheriff George F. Johnson IV, a Democrat who has more than $318,000 on hand for his campaign for executive.
