The New Hampshire primary is the first in a series of nationwide party primary elections held in the United States every four years as part of the process of choosing the delegates to the Democratic and Republican national conventions which choose the party nominees for the presidential elections to be held the subsequent November.

Although only a few delegates are chosen in the New Hampshire primary, its real importance comes from the massive media coverage it receives (along with the first caucus in Iowa); in recent decades the two states received about as much media attention as all other state contests combined. An example of this massive media coverage has been seen on the campus of Saint Anselm College, as the campus has held multiple national debates and have attracted media outlets like Fox News, CNN, NBC, and ABC. The publicity and momentum can be enormous from a decisive win by a frontrunner, or better-than-expected result in the New Hampshire primary. The upset or weak showing by a front-runner changes the calculus of national politics in a matter of hours, as happened in 1952 (D), 1968 (D), 1980 (R), and 2008 (D).

New Hampshire (ⁱ/njuːˈhæmpʃər/) is a state in the New England region of the northeastern United States of America. The state was named after the southern English county of Hampshire. It is bordered by Massachusetts to the south, Vermont to the west, Maine and the Atlantic Ocean to the east, and the Canadian province of Quebec to the north. New Hampshire is the 5th least extensive and the 9th least populous of the 50 United States.

It became the first post-colonial sovereign nation in the Americas when it broke off from Great Britain in January 1776, and six months later was one of the original thirteen states that founded the United States of America. In June 1788, it became the ninth state to ratify the United States Constitution, bringing that document into effect. New Hampshire was the first U.S. state to have its own state constitution.

It is known internationally for the New Hampshire primary, the first primary in the U.S. presidential election cycle. Concord is the state capital, while Manchester is the largest city in the state. It has no general sales tax, nor is personal income (other than interest and dividends) taxed at either the state or local level.

Hampshire (ⁱ/ˈhæmpʃɪər/ or /ˈhæmpʃər/; abbreviated Hants) is a county on the southern coast of England in the United Kingdom. The county town of Hampshire is Winchester, the former capital city of England. Hampshire is the most populous ceremonial county in the United Kingdom and if excluding newly formed metropolitan counties such as the West Midlands, Hampshire would be the most populous county in the whole of the United Kingdom. Hampshire is notable for housing the birthplaces of the Royal Navy, British Army, and Royal Air Force. The ceremonial county borders Dorset to the west, Wiltshire to the north-west, Berkshire to the north, Surrey to the north-east, and West Sussex to the east. The southern boundary is the coastline of the English Channel and The Solent.

Hampshire is the largest county in South East England and the third largest shire county in the United Kingdom despite losing more land than any other English county during the Local Government Act 1972 boundary changes. At its greatest size in 1889, Hampshire was the fifth largest county in England. It now has an overall area of 3,700 square kilometres (1,400 sq mi), and measures approximately 86 kilometres (53 mi) east–west and 76 kilometres (47 mi) north–south.
