Rep. Edith Tucker, D-Randolph, has announced her candidacy for the District 1 state senate seat. Tucker, 84, is in her third term representing the Coos 5 district (Carroll, Jefferson, Randolph and Whitefield), and serves on the powerful House Ways and Means Committee. The longtime local journalist is running to provide strong, experienced and effective representation for Coos County and upper Grafton County. Tucker is the first Democrat to enter the Senate 1 race. Republicans state Rep. Troy Merner, of Lancaster, and Select Board member Carrie Gendreau, of Littleton, have already declared. They seek to replace first-term Sen. Erin Hennessey, R-Littleton, who is stepping down to spend time with family and won’t seek re-election.
