Ohio: The State That Decided Everything
As in 2000, the entire election came down to a single state. Bush won Ohio by 118,601 votes out of 5.6 million cast — a margin of 2.1 percentage points. Ohio had 20 electoral votes. If Kerry had carried Ohio, the final electoral count would have been Kerry 271 to Bush 266. John Kerry would have been president.
Kerry narrowly lost Ohio in the Cleveland and Columbus suburbs, where he underperformed Democratic expectations. Bush's campaign focused heavily on mobilizing evangelical Christians and rural Ohioans on cultural issues — gay marriage ballot initiatives in 11 states, including Ohio, drove unusually high conservative turnout.
On election night, Kerry and his team initially believed provisional ballot counts might close the gap in Ohio. By early morning on November 3, Kerry's campaign concluded the provisional votes were insufficient and Kerry conceded, making the 2004 race one of the few modern elections decided on election night despite enormous pre-election uncertainty.

What Decided 2004
Iraq War Framing — Wartime President vs. Flip-Flopper
Bush's campaign successfully framed the election as a wartime leadership test. Kerry, who had voted to authorize the Iraq War but later criticized its execution, was hammered relentlessly as a "flip-flopper." Bush's team produced the famous "windsurfing" ad showing Kerry changing direction, and the message that changing commanders mid-war was dangerous stuck with persuadable voters. Kerry's nuanced position — "I voted for it before I voted against it" — became one of the most damaging self-inflicted soundbites in modern campaign history.
Swift Boat Veterans
The Swift Boat Veterans for Truth ran ads questioning Kerry's Vietnam War record, despite his having earned the Silver Star, Bronze Star and three Purple Hearts. The campaign was coordinated, well-funded and launched in August — a critical period when campaigns are being defined. Kerry's team was slow to respond, apparently calculating that the attacks were so factually thin they would collapse on their own. They did not. The phrase "swift-boating" entered the political lexicon as a term for attacking a candidate's perceived strength.
Gay Marriage Ballot Initiatives in 11 States
Republican strategist Karl Rove placed constitutional amendments banning gay marriage on the ballot in 11 states, including the critical battleground of Ohio. The measures drove unusually high turnout among evangelical Christian voters and rural conservatives who might not otherwise have come to the polls. Exit polls showed "moral values" was the top issue for Bush voters in 2004, cited by 22% — more than terrorism, the economy or Iraq. The strategy was highly effective and ethically controversial.
The Osama bin Laden Tape — October 29, 2004
Four days before Election Day, Osama bin Laden released a video address directly to the American people, acknowledging for the first time that he had personally ordered the September 11 attacks. The tape dominated the final days of the campaign and reminded voters of the terrorism threat at a moment when Kerry had begun to close the gap. Most post-election analyses concluded the tape shifted the race back toward Bush by reinforcing his national security advantage.
The 9/11 National Security Premium
Three years after September 11, terrorism remained the dominant concern for a plurality of American voters. Bush held a consistent double-digit advantage over Kerry on the question of who was better suited to handle terrorism and national security. In a post-9/11 electorate, this was a decisive structural advantage for any incumbent president. Bush's campaign consistently emphasized that America was at war and that changing leadership mid-conflict was reckless — a frame Kerry never fully overcame.
Frequently Asked Questions
Was the 2004 election close?
Very close. Bush won Ohio by only 118,601 votes out of 5.6 million cast. Ohio had 20 electoral votes. If Kerry had carried Ohio, the final tally would have been Kerry 271 to Bush 266 — making Kerry president. The popular vote was also close: Bush 50.7% to Kerry 48.3%, a margin of roughly 3 million votes nationally. It was the first election since 1988 in which the winner crossed 50% of the popular vote.
What were the Swift Boat ads?
The Swift Boat Veterans for Truth ran a series of attack ads in August 2004 questioning John Kerry's Vietnam War record, despite his having earned the Silver Star, Bronze Star and three Purple Hearts. Independent fact-checkers found the ads were misleading or false, but they landed during a period when the Kerry campaign did not respond aggressively. The phrase "swift-boating" has since become political shorthand for attacking a candidate at their perceived point of greatest strength with misleading or false information.
How did 9/11 affect Bush's re-election?
The September 11 attacks created a sustained national security premium that benefited Bush. In 2004, terrorism was the top concern for a significant plurality of voters and Bush led Kerry by double digits on who was better suited to handle it. Bush's campaign framed him as a wartime commander whose leadership should not be interrupted mid-conflict. An Osama bin Laden tape released four days before the election reinforced these fears at a critical moment and is widely believed to have helped close a race that Kerry had been tightening.
