New Hampshire Political History & Voting Patterns
Historically R (Yankee); flipped D with migration from MA in 1990s-2010s. A complete guide to how New Hampshire has voted in presidential elections, which coalitions have driven results, and how the state has shifted over time.
Historical Overview
New Hampshire was the heartland of Yankee Republicanism — the ’Live Free or Die’ state that resisted income and sales taxes and prided itself on fiscal conservatism. The first-in-the-nation primary gave it outsized national influence. But Massachusetts emigration transformed southern New Hampshire’s politics; by 2006, Democrats swept the state legislature for the first time in history. New Hampshire swings between parties more than any other New England state. The 2000 election, where Bush won by 7,282 votes and Al Gore would have won the presidency without NH, remains the counterfactual that haunts Democrats. Jeanne Shaheen’s retirement creates a competitive open Senate seat in 2026.
