The 2000 United States presidential election in New Hampshire took place on Election Day on November 7, 2000, as part of the 2000 United States presidential election. The two major candidates were Texas GovernorGeorge W. Bush of the Republican Party and Vice President Al Gore of the Democratic Party. When all votes were tallied, Bush was declared the winner with a plurality of the vote over Gore, receiving 48% of the vote to Gore's 47%, while Green Party candidate Ralph Nader received almost 4% of the vote in the state. Bush went on to win the election nationwide. Had incumbent Gore come out victorious in New Hampshire with its four electoral votes, he would have won the presidency, regardless of the outcome of Bush v. Gore.
As of the 2020 presidential election, this is the only time since 1988 that the Republican nominee carried New Hampshire, making it the only state to vote for the Republican ticket in 2000 never to do so again since, as every other state Bush won in 2000 voted for him again in 2004. It also marked the last time that a Republican won any electoral votes in New England until Donald Trump won Maine's 2nd congressional district in 2016 and 2020, and the last time a Republican won any state in the Northeastern United States until Donald Trump won Pennsylvania in 2016.
Bush was the first Republican since 1888 to win without Merrimack County, the first since 1880 to win without Grafton County, and the first ever to win without Cheshire County.
