Birdsell beat out her Democratic challenger Joshua Bourdon of Derry in Tuesday's election by a total vote count, in early unofficial results, of 18,262 to 13,477.

Carson has served 12 years in the New Hampshire state Senate and before that served eight years in the state House of Representatives.
Hendricks served many years on the Londonderry School Board, including years as its chairman.
This will be Birdsell's fourth term in the state Senate.
Before serving in the Senate, Birdsell served two terms in the New Hampshire House of Representatives (2010-14).
Bourdon, a Derry town councilor, thanked Birdsell in a statement on social media after the election and wished her good luck in her return to the Senate.
