Republican Senate President Ted Gatsas is facing a stronger challenger this year in the race for the 16th District.
The district includes the northern three wards of Manchester as well as Bow, Candia, Dunbarton and Hooksett.
Two years ago, a confident Senator Gatsas won with 61% of the vote.
Four years ago, he took 63%.
But in this year's race, the three term incumbent may be keeping an eye on who's trailing.
