It might be remembered for the plexiglass, or for the relative tameness, or perhaps not at all given the chaos back in Washington and the frenetic pace of the campaign as a whole.

Or it might be remembered for searing attacks not just on opposing plans but on entirely different portrayals of the past and visions of the near future, amid a pandemic that seldom has felt more urgent.

At a moment of intense focus on the health of a president, and with two historically old candidates topping the ticket, the running mates engaged in an emotional and highly personal debate – just one lacking the insults and outsized personalities of President Donald Trump and former Vice President Joe Biden.

The vice presidential candidates for president faced off on Wednesday for their first and only debate, giving Americans a much more substantive look at the ticket — though often not the substance that they were prompted for.

The candidates repeatedly dodged the questions from moderator Susan Page, remaining focused on one thing: correcting the wrongs of last week’s debate.

Here are the key takeaways.

PENCE'S CLAIM: "President Trump and I are fighting every day in courthouses to prevent Joe Biden and Kamala Harris from changing the rules and creating this universal mail-in voting that will create a massive opportunity for voter fraud."

FACT CHECK: Pence echoed Trump's attempts to cast doubt on the widespread embrace of vote-by-mail across the country this election by suggesting that universal mail-in voting could lead to massive fraud.

That is historically not true.

Kim Wyman, the Republican secretary of state in Washington -- a state that adopted statewide mail voting in 2011 -- told The New York Times in June that while any voting method could potentially be susceptible to fraud, in her experience as the chief elections official in the state, fraud with mail ballots is low.

"How do you respond to someone that makes an allegation that there's rampant fraud?" she said. "You show them all the security measures that are in place to prevent it and detect it if it does happen."

Ben Ginsberg, a Republican election guru who has spent years looking for voter fraud, wrote in a Washington Post op-ed, "Four decades of dedicated investigation have produced only isolated incidents of election fraud."

"These are painful conclusions for me to reach. Before retiring from law practice last month, I spent 38 years in the GOP's legal trenches. I was part of the 1990s redistricting that ended 40 years of Democratic control and brought 30 years of GOP successes in Congress and state legislatures. I played a central role in the 2000 Florida recount and several dozen Senate, House and state contests," he wrote. "The truth is that after decades of looking for illegal voting, there's no proof of widespread fraud."

Tom Ridge, a Republican who previously served as the governor of Pennsylvania and was the nation's first secretary of Homeland Security, previously told ABC News, "There is absolutely no antecedent, no factual basis for (President Donald Trump's) claim of massive fraud in mail voting."

PENCE'S CLAIM: "It's probably why Newsweek magazine said that Kamala Harris was the most liberal member of the United States Senate in 2019, more liberal than Bernie Sanders, more liberal than any of the others in the United States Senate."

FACT CHECK: Harris certainly has a very liberal Senate voting record, and an analysis cited by Newsweek in 2019 did find her to be the most liberal in the U.S. Senate.

However, that particular analysis does not consider some important caveats, the founder of the organization who conducted it told ABC News.

, an independent and nonpartisan group, found that Harris was the "most liberal" of her Senate colleagues in a 2019 survey, which compared the number of bipartisan bills a senator co-sponsored to the total number of bills he or she signed onto. Harris had the smallest percent of bipartisan bills in 2019, making her the most-liberal senator by this metric.

Harris certainly has one of the more liberal voting records in the Senate: She has voted to increase gun control and block conservative judicial nominees, for instance.

But there are nuances that the organization's founder, Jonathan Tauberer, said GovTrack's model doesn't account for, like the complexity of Harris' political views, the distinctions between different wings within each major political party, the specific approach Harris might take to achieve her desired outcome, or the unwillingness of Republicans to work with Harris during a presidential year.

PENCE'S CLAIM: "When President Trump and I took office, America had gone through the slowest economic recovery since the great depression. ... We're going through a pandemic that lost 22 million jobs at the height, we've already added back 11.6 million jobs."

FACT CHECK: With September's jobs report, over 11.4 million jobs have been added since March. But job gains have slowed in the past three months, showing the recovery is starting to lose momentum.

In September, 661,000 jobs were added, which was worse than expectations. The unemployment rate also declined to 7.9%, better than expectations.

The jobs number represented a significant slowdown in the number of jobs added since the economy started opening up after the pandemic induced shutdown.

Airlines such as United and American notified over 30,000 employees that they would be laid off or furloughed because the federal aid expired. Disney, the parent company of ABC News, announced it was eliminating 28,000 theme park jobs in Florida and California, and Cineworld, parent company of Regal Cinemas, the second-largest theater chain in the United States, said Monday that it will close all of its U.S. and U.K. theaters indefinitely, affecting 45,000 employees. These positions weren't included in the September report.

In September, the number of permanent job losses increased by 345,000 to 3.8 million; this measure has risen by 2.5 million since February.

Though the expansion of the U.S. economy was slow under the start of the Obama administration during the Great Recession, in the final four years GDP growth was at a 2.3%, nearly similar to the 2.5% in the first three years of Trump, according to The Associated Press.
