History

New Hampshire held its first primary on the second Tuesday of March in 1916, along with Minnesota. Indiana held its primary a week earlier. New Hampshire became first-in-the-nation in 1920 when Indiana moved its date to May and Minnesota returned to a caucus.
 
New Hampshire legislators felt it more sensible to hold the primary on the traditional town meeting day, prompting the state's first in the nation status. Representatives Stephen Bullock (D- Richmond) and John Glessner (R- Bethlehem) drafted the primary law which facilitated the date change from the third Tuesday in May to the second Tuesday in March.
 
The idea of New Hampshire's Presidential primary grew out of the progressive reform movement early in the last century. It was an effort to move the decision-making process on the party's Presidential nominee away from the party caucus to a state run election so as many voters as possible would factor in deciding on the nominee.
 
In another effort to increase voter participation, Speaker of the House Richard Upton wrote legislation in 1949 enabling New Hampshire voters to vote directly for a Presidential candidate rather than a delegate pledged to a Presidential candidate.
 
With the increasing use of television in Presidential campaigns in the 1960's, the nation began to realize the role of each state in the Presidential selection process. The idea of the importance of being first-in-the-nation took on new meaning. New Hampshire passed state law in 1975 that gave the Secretary of State sole authority to set the date of the New Hampshire primary and required the Secretary of State to set the date one week before any other similar contest.
 
The state's primary law was modified in 1999 to give greater flexibility to the Secretary of State by stipulating seven days or more ahead of any similar election, allowing the term “similar” to be interpreted by the Secretary of State. This allows discretion by the Secretary of State to determine if a primary or a caucus in another state is a similar election. New Hampshire law allows for Iowa to precede New Hampshire because it is a caucus, not a statewide presidential primary election.
