CONCORD, N.H. (AP) - New Hampshire's first-in-the-nation presidential primary is turning 100.

Tuesday marks 100 years since the New Hampshire Legislature passed, and the governor signed, legislation creating the state's presidential primary. Under that law, the state switched from a caucus system to a primary, and any potential delegate was allowed to be listed on a statewide ballot for election to the national convention. Candidates were permitted to sign up either as pledged to a particular presidential candidate or as uncommitted.

To mark the anniversary, Gov. Maggie Hassan, Secretary of State Bill Gardner and others are holding a public birthday celebration at the Statehouse. The celebration will include a special presentation by the family of Rep. Stephen Bullock, who wrote the original legislation.
