“While I’ll be a Democratic candidate, I will be an American president,” Biden said in his remarks. “I’ll work hard for those who didn’t support me, as hard for them as I did for those who did vote for me.”

The former vice president said that President Donald Trump has “cloaked America in darkness for much too long.”

“Too much anger,” he said. “Too much fear. Too much division.”

“If you entrust me with the presidency, I will draw on the best of us, not the worst,” Biden continued. “I’ll be an ally of the light, not the darkness. It’s time for us — for we the people — to come together.”

Biden noted that America is facing “four historic crises,” including the coronavirus pandemic, the economic recession, racial injustice and the ongoing protests to end it, and climate change.

“Just judge this president on the facts,” Biden said of Trump before listing the number of Americans infected with COVID-19 (over 5 million) and the number of Americans who have been killed by the virus (more than 173,000).

“If this president is reelected, we know what will happen. Cases and deaths will remain far too high,” Biden said.

His remarks culminated four days of impassioned and emotional pleas from prominent Democrats and politicians, many warning that four more years of Trump’s administration loom as an existential threat to U.S. democracy.

Much of Biden’s message adhered to the theme of the convention’s slogan that urged Americans to create a “more perfect union” and highlighted the effects of Trump’s divisive rhetoric on the country.

Biden recalled the violent white supremacist demonstration that brought “neo-Nazis and Klansmen” to Charlottesville, Virginia, in 2017.

“Remember what the president said? There were quote, ‘very fine people on both sides,’” Biden said.

“It was a wake-up call for us as a country. And for me, a call to action,” the candidate said. “At that moment, I knew I’d have to run. My father taught us that silence was complicity. And I could not remain silent or complicit.”

“At the time, I said we were in a battle for the soul of this nation,” he said. “And we are.”

Earlier this month, Biden tapped Sen. Kamala Harris of California to be his running mate. Since then, the pair have focused fire on Trump and his administration while also fleshing out their own biographies for voters.

While Biden’s speech was the centerpiece of the convention, he made appearances several times during the virtual event, including Tuesday night after his wife, Jill Biden, gave a speech touting her 77-year-old husband’s commitment to public service, even as he much personal grief in his life.

The former vice president in Barack Obama’s administration also briefly appeared on stage with Harris after she gave her acceptance speech Wednesday night in Delaware, Biden’s home state which he represented in the Senate for 36 years.

Biden’s presidential bid got off to a rocky start when he ran poorly in the opening nominating contests in Iowa and New Hampshire. But he turned his campaign around with an impressive win in the South Carolina primary on Feb. 29. He then dominated the rest of the primary campaign, which took an unexpected turn in late March when the coronavirus pandemic forced him and the other remaining candidates to cease large rallies and in-person politicking.

As the Nov. 3 election day nears, Biden’s campaign is focusing not only on battleground states, but on some Republican-leaning states where polls have shown him competitive against Trump. In early August, his team announced plans to spend $280 million in TV ads across Pennsylvania, Michigan, Wisconsin, Florida, North Carolina, Arizona, Minnesota, Nevada, New Hampshire, Colorado, Virginia, Georgia, Iowa, Ohio and Texas.
