A special election to replace state Sen. Thomas M. McGee will be held on Tuesday, March 6.
Voters in Lynn, Lynnfield, Marblehead, Nahant, Saugus, and Swampscott will choose a new senator as McGee becomes the next mayor of Lynn.
The primary is scheduled for Tuesday, Feb. 6.
Last week, McGee, who served on Beacon Hill since 1995, defeated Mayor Judith Flanagan Kennedy in her bid for a third term.
Candidates have until Dec. 26 to file nomination papers locally and then face a Jan. 2 deadline to submit certified nomination papers with Secretary of State William Galvin.
So far, the only declared candidate is state Rep. Brendan Crighton (D-Lynn).
