The state gambling commission made two key hires on Tuesday, borrowing Patrick administration official C. Stanley McGee to serve as the board’s interim executive director, and voting to offer Boston Police spokeswoman Elaine B. Driscoll the post as the commission’s first director of communication. McGee, 43, of Boston, is the assistant secretary for policy and planning in the governor’s Executive Office of Housing and Economic Development. He has been one of Governor Deval Patrick’s key policy advisors on gambling issues.
