After watching a Donald Trump campaign rally in Wilkes-Barre, Pennsylvania, in October, Vice President Joe Biden says that was the moment he realized Donald Trump would defeat Hillary Clinton in November's election.

That's what the vice president told the Los Angeles Times in a recent interview.

"Son of a gun. We may lose this election," Biden told the Times, recounting his reaction after watching the rally from his White House office.

"They’re all the people I grew up with. They’re their kids. And they’re not racist. They’re not sexist. But we didn’t talk to them," the vice president added.

Reflecting on Trump's connection with Americans throughout his campaign, and during that Pennsylvania rally in October, Biden attempted to diagnose Democrats' inability to connect with middle America.

"My dad used to have an expression. He said, ‘I don’t expect the government to solve my problems. But I expect them to understand it," Biden said, adding that he doesn't believe Democrats are positioning themselves to "understand" the struggles of "an awful lot of people."

"I was trying to be as tactful as I could in making it clear that I thought we constantly made a mistake of not speaking to the fears, aspirations, concerns of middle class people," Biden went on to comment, explaining his central message during his 83 campaign stops for Clinton.

It was that message — one that connected with middle-class voters — that Biden wanted to bring to his own presidential campaign, he told the Times. However, Biden decided late last year not to run for the White House.
