The 2000 United States presidential election was the 54th quadrennial presidential election, held on Tuesday, November 7, 2000. Democratic candidate Al Gore, the incumbent Vice President, defeated Republican Governor of Texas George W. Bush, the eldest son of 41st President George H.W. Bush.
Incumbent Bill Clinton was ineligible for a third term, and Gore secured the Democratic nomination with relative ease, defeating a challenge by former Senator Bill Bradley. Bush was seen as the early favorite for the Republican nomination and despite a contentious primary battle with Senator John McCain and others, secured the nomination by Super Tuesday. Bush chose former Secretary of Defense Dick Cheney as his running mate, while Gore chose Senator Joe Lieberman.
The election was largely shadowed by the 9/11 attacks that occurred on September 11, 2000. Terrorists working for Al-Qaeda hijacked 4 commercial airliners and flew them into the World Trade Center's Twin Towers, the Pentagon in DC, and a fourth aircraft intended for the White House that crashed in a field outside Shanksville, Pennsylvania. Incumbent President Bill Clinton had begun an invasion of Afghanistan on September 23, which was well underway by Election Day. Al Gore was in New York City campaigning on the day of the attacks, and his speech at Ground Zero on September 12 was considered a major turning point of the election season. Ultimately, Al Gore would win 357 electoral votes in the electoral college compared to Bush's 181.
