Vice President Al Gore and Gov. George W. Bush engage in their first presidential debate, a 90-minute match at the Clark Athletic Center of the University of Massachusetts.

George Bush, considered a lightweight, probably won by not losing, many would later write. But Vice President Gore, while more knowledgeable about the issues, came off as smug and condescending. The New York Times would later write that this seminal debate lost Vice President Gore the presidency, with a rich oral history of those involved speaking in 2016 of the lessons to be learned before the first Clinton-Trump debate.

“We felt the first debate would be his moment—that people would see two candidates on stage, but only one president,” said Tad Devine, Gore senior advisor. But as the debate got underway, Gore showed his contempt and impatience for Bush. “Gore was … sighing and reacting to Bush, and there were lots of reaction shots. It was somewhat inexplicable —as if the things that Gore had been told not to do became his to-do list,” said Robert Shrum, one of Gore’s senior advisors. “I didn’t think Gore’s sighs were a really big deal until I got to the spin room,” Shrum said. The Gore campaign soon found out that many thought Gore had blown it.
