Biden said if he is elected he would pass Obamacare with a public option, deeming it "Bidencare," and outlining his plan.

"If you qualify for Medicaid and you do not have the wherewithal in your state to get Medicaid, you're automatically enrolled, providing competition for insurance companies," Biden said.

"Secondly, we're going to make sure we reduce the premiums and reduce drug prices by making sure that there's competition that doesn't exist now, by allowing Medicare to negotiate drug prices with the insurance companies," he said.

Biden said private insurance would be protected under his plan.

"Thirdly, the idea that I want to eliminate private insurance -- the reason why I had such a fight for -- with 20 candidates for the nomination, was I support private insurance," Biden said. "Not one single person with private insurance would lose their insurance under my plan, nor did they under Obamacare."

"Lastly, we're going to make sure we're in a situation that we actually protect pre-existing conditions. There's no way he can protect pre-existing conditions. None. Zero," Biden said, as the Trump administration seeks to dismantle the entire Affordable Care Act which currently protects them.

Trump said earlier, "I'd like to terminate Obamacare, come up with a brand-new beautiful health care."

With unprecedented unemployment in the United States, where health care is inextricably linked to employment, and a coronavirus pandemic ravaging the globe, it's safe to say that on Nov. 3, health is on the ballot.

As it stands, more than 220,000 Americans have died of COVID-19. Another roughly 13 million are unemployed.

Health might be a political football in 2020, but it's also a deeply personal issue that affects every American voter. Given health's crucial significance this year, the nonprofit Commonwealth Fund polled 4,220 likely voters in battleground states between Aug. 25 and Sept. 20 on which health care issues mattered most to them, and which candidate -- Trump or Biden -- they thought would be more likely to address those health concerns.

Here's what the American public said about which health care issues they care about.

BIDEN'S CLAIM: "The expectation is we'll have another 200,000 Americans dead in the time between now and the end of the year. If we just wore these masks, the president's own advisers have told him, we could save 100,000 lives."

FACT CHECK: The president's advisers haven't used this estimate, though the head of the Centers for Disease Control and Prevention has strongly recommended wearing them. A modeling study by the University of Washington estimated at one point that if most Americans wore masks, it could save 100,000 lives by the end of the year. That estimate has been repeated by Tom Frieden, who led the CDC under President Barack Obama.

Dr. Robert Redfield, the current head of the CDC under Trump, has not made such a statement.

According to his office, he has said that the pandemic could begin to come under control in eight to 12 weeks "if all people living in America wore a face mask, were smart about social distancing and crowds, and practiced good hand hygiene."

Trump and Biden took questions on how to deal with China more broadly amid transparency concerns with the Chinese government. After Biden said he would make China “play by the international rules,” Trump touted $28 billion in subsidies given to farmers during his administration affected by the U.S.-China trade war.

“First of all, China is paying. They're paying billions and billions of dollars. I just gave $28 billion to our farmers,” Trump said, before Biden interrupted, “That’s taxpayers' money.”

Given a chance to respond, Biden turned to families at home.

“There's a reason why he's bringing up all this malarkey. There's a reason for it. He doesn't want to talk about the substantive issues. It's not about his family and my family. It's about your family and your family is hurting badly,” Biden said.

“Are we going to be able to pay the mortgage? Who's going to tell her she can't go back to community college? They're the decisions you're making in the middle-class families like I grew up in Scranton and Claymont. They're in trouble. We should be talking about your families, but that's the last thing he wants to talk about,” Biden added.

Trump scoffed at Biden's answers and took the chance to define himself as not another “typical politician.”

“That is a typical statement,” Trump responded. “That's a typical political statement. Let's get off this China thing. He looks at the family around the table, just a typical politician. I'm not a typical politician. That's why I got elected. Let's get off the subject of China. Let's talk around sitting around the table. Come on, Joe. You can do better.”

TRUMP'S CLAIM: “When I closed, he said, 'This is a terrible thing. You're xenophobic.' I think he called me racist, even, and -- because I was closing it to China. Now, he says I should have closed it earlier. It just -- Joe, it doesn't work."

FACT CHECK: While Trump claimed that Biden opposed his decision to ban most travel from China at the outset of the coronavirus pandemic and that he called the restrictions "xenophobic," the former vice president did not explicitly weigh in on the decision when it was announced on Jan. 31. He did call the president xenophobic minutes after the partial travel ban was announced, but did not call Trump a racist for the decision.

During a campaign event that same day in Fort Madison, Iowa, Biden discussed the growing concern over the COVID-19 outbreak and cautioned that Trump should let science "lead the way."

"In moments like this, this is where the credibility of a president is most needed as he explains what we should and should not do," Biden told the crowd at the event. "This is no time for Donald Trump's record of hysterical xenophobia ... and fear-mongering to lead the way instead of science."

The comments came just minutes after the White House announcement, so it was unclear if Biden was referring to the decision specifically, but the former vice president did tweet a similar sentiment the next day.

"We are in the midst of a crisis with the coronavirus," Biden posted. "We need to lead the way with science -- not Donald Trump's record of hysteria, xenophobia, and fear-mongering. He is the worst possible person to lead our country through a global health emergency."

Throughout March, Biden used the word "xenophobic" in various speeches and tweets to criticize the president labeling COVID-19 as the "China virus."

Biden did acknowledge the travel restrictions put in place by the Trump administration in a March speech, noting they "may" slow the spread.

"Banning all travel from Europe or any other part of the world may slow it, but as we've seen, it will not stop it. And travel restrictions based on favoritism and politics rather than risk will be counterproductive," Biden said.

Biden's campaign did not explicitly discuss the vice president's view of the ban until April.

"Joe Biden supports travel bans that are guided by medical experts, advocated by public health officials and backed by a full strategy," Biden's deputy campaign manager Kate Bedingfield told CNN. "Science supported this ban, therefore he did too.
