WASHINGTON (AP) 鈥� It could be a well-rehearsed zinger or an offhand, too-loud sigh.
Notable moments from demonstrate how the candidates' words and body language can make them look especially relatable or hopelessly out-of-touch. They also can showcase candidates at the top of their policy game or suggest they're out to sea.
Will past be prologue when President Joe Biden and former President Donald Trump debate in Atlanta on Thursday?
鈥淒ebates, being live television events, without a script, without any way of knowing how they are going to evolve 鈥� anything can happen,鈥� said Alan Schroeder, author of 鈥淧residential Debates: 50 years of High-Risk TV.鈥�
Here's a look at some standout high moments, low moments and curveballs from presidential debates past.
That old age questi
on (again)
When everyone knows a sensitive question is coming yet you make the answer sound spontaneous, you're having a good debate. Republican President Ronald Reagan landed a line for the ages in the second presidential debate of 1984 after an underwhelming opening matchup.
Reagan was 73 and seeking a second term in his race against Democratic challenger Walter Mondale, then 56. In the first debate, Reagan struggled to remember facts and occasionally looked befuddled.
One of his top advisers, Nevada Sen. Paul Laxalt, suggested afterward that aides 鈥渇illed his head with so many facts and figures that he lost his spontaneity."
So Reagan's team took a more hands-off approach toward his second faceoff with Mondale. And, when Reagan got a question about his mental and physical stamina that he had to know was coming, he was ready enough to make the response feel unplanned.
鈥淵ou already are the oldest president in history,鈥� moderator Henry Trewhitt said before asking whether Reagan might not be able to handle a challenge like the Cuban missile crisis.
鈥淣ot at all,鈥� Reagan responded in defense of his crisis management smarts. He smoothly continued, 鈥淚 want you to know that, also, I will not make age an issue of this campaign. I am not going to exploit, for political purposes, my opponent鈥檚 youth and inexperience.鈥�
Then, capitalizing on years of Hollywood-honed comedic training, the president took a sip of water, giving the audience and even Mondale, who himself cracked up, more time to laugh. Finally, he grinned and left little doubt that he'd rehearsed a response, adding, "It was Seneca, or it was Cicero, I don鈥檛 know which, that said, 鈥業f it was not for the elders correcting the mistakes of the young, there would be no state.鈥欌��
Years later, Mondale said that while TV viewers saw him laughing, 鈥淚 think, if you come in close, you鈥檒l see some tears coming down, because I knew he had gotten me there. That was really the end of my campaign that night."
Reagan thereby proved that even at his age, a candidate could get better over time. And with this year's race pitting 81-year-old Biden against 78-year-old Trump, 73 doesn't seem so old anymore.
Reagan is also remembered for using a light touch to neutralize criticisms from Democratic President Jimmy Carter in a 1980 debate.
When Carter accused him of wanting to cut Medicare, Reagan scolded, 鈥淭here you go again.鈥� The line worked so well he turned it into something of a trademark rejoinder going forward.
Gaffes galore
In 1976, Republican President Gerald Ford had a notable moment during his second debate against Carter 鈥� and not in a good way. The president declared that there is 鈥渘o Soviet domination of Eastern Europe and there never will be under a Ford administration.鈥�
With Moscow controlling much of that part of the world, moderator Max Frankel responded, 鈥淚'm sorry, wha..?鈥� and asked if he'd understood correctly. Ford stood by his answer, then spent days on the campaign trail trying to explain it away. He lost that November.
鈥淭he closer the election, the more zingers and important debate lines can matter,鈥� said Aaron Kall, director of the debate program at the University of Michigan. 鈥淣ot just on who won, or who lost, but how does it affect fundraising, how does it impact the media cycle in coming days and weeks.鈥�
Not all slips of the lip have a devastating impact.
Then-Sen. Barack Obama, in a 2008 Democratic presidential primary debate, dismissively told Hillary Clinton, 鈥淵ou鈥檙e likable enough, Hillary.鈥� That haughty answer drew a backlash but Obama recovered.
The same couldn鈥檛 be said for the short-lived 2012 Republican White House bid of then-Texas Gov. . Despite repeated attempts and excruciatingly long pauses, Perry could not remember the third of the three federal agencies he鈥檇 promised to shutter if elected.
Finally, he sheepishly muttered, 鈥淥ops.鈥�
The Energy Department is what slipped his mind.
Getting personal
Another damaging moment opened the second presidential debate in 1988, when CNN anchor Bernard Shaw pressed Democrat Michael Dukakis, the governor of Massachusetts, about his opposition to capital punishment with a question that evoked the candidate's wife.
鈥淚f Kitty Dukakis were raped and murdered, would you favor an irrevocable death penalty for the killer?鈥� Shaw asked. Dukakis showed little emotion as he responded, 鈥淚 don鈥檛 see any evidence that it鈥檚 a deterrent.鈥�
Dukakis later said he wished he'd said that his wife "is the most precious thing, she and my family, that I have in this world."
That year's vice presidential debate featured one of the best-remembered, pre-planned one-liners.
When Dan Quayle, the Republican vice presidential nominee and Indiana senator, compared himself to John F. Kennedy while debating Texas Sen. Lloyd Bentsen, the Democrat was ready. He'd studied Quayle's campaigning and seen him invoke Kennedy in the past.
鈥淪enator, I served with Jack Kennedy. I knew Jack Kennedy,鈥� Bentsen began slowly and deliberately, drawing out the moment. 鈥淛ack Kennedy was a friend of mine. Senator, you鈥檙e no Jack Kennedy.鈥�
The audience erupted in applause and laughter. Quayle was left to stare straight ahead.
Blunders without words
Quayle and George H.W. Bush still easily won the 1988 election. But they lost in 1992 after then-President Bush was caught on camera looking at his watch while Democrat Bill Clinton talked to an audience member during a town hall debate. Some thought it made Bush look bored and aloof.
In another instance of a nonverbal debate miscue, then-Democratic Vice President Al Gore was criticized for a subpar opening 2000 debate performance with Republican George W. Bush in which he repeatedly and very audibly sighed.
During their second, town hall-style debate, Gore moved so close to Bush while the Republican answered one question that Bush finally looked over and offered a confident nod, drawing laughter from the audience.
A similar moment occurred in 2016, as Hillary Clinton faced the audience to answer questions during her second debate with Trump. The Republican candidate moved in close behind her, narrowed his eyes and glowered.
Clinton offered no visible reaction then, but later wrote of the incident, "He was literally breathing down my neck. My skin crawled.鈥�
Biden-Trump redux
Thursday鈥檚 faceoff will be the first time a current president debates a former.
Historically, incumbents sometimes struggle during opening debates. They're used to being surrounded by White House advisers who offer little pushback. In 2012, then-President Obama鈥檚 seemingly detached first debate performance against Mitt Romney allowed the Republican to gain momentum.
Romney, though, had an awkward moment during the second debate.
Answering a question about gender pay equity, the former Massachusetts governor talked about going to women's groups to get help finding qualified female applicants for top state posts.
"They brought us whole binders full of women,鈥� he declared. Obama turned that into an attack line at subsequent rallies, gleefully saying, 鈥淲e don't have to collect a bunch of binders to find qualified, talented, driven young women.鈥�
If Biden's debate skills are rusty this time, his opponent's might be as well. Trump skipped all the GOP primary debates this time, meaning he鈥檚 not done one since squaring off with Biden twice in 2020.
Trump interrupted so frequently when they first debated four years ago that Biden eventually cried out, 鈥淲ill you shut up, man?鈥� 鈥� a visceral moment if there ever was one. Trump is remembered that night for instructing members of the far-right group from the stage to 鈥渟tand back and stand by.鈥� Some members of the extremist group took it as a sign of encouragement.
The of 2020 saw producers cut the mics to discourage interrupting, making it less chaotic. It featured Biden wistfully declaring, 鈥淚 am anxious to have this race. I鈥檓 anxious to see this take place.鈥�
It did. And now it's happening again.
