AP: Former Vice President Joe Biden formally joined the crowded Democratic presidential contest on Thursday, betting that his working-class appeal and ties to Barack Obama’s presidency will help him overcome questions about his place in today’s increasingly liberal Democratic Party.
He made his announcement in a video posted on Twitter, declaring, “We are in the battle for the soul of this nation.”
"If we give Donald Trump eight years in the White House, he will forever and fundamentally alter the character of this nation," Biden said. "Who we are. And I cannot stand by and watch that happen."
"Everything that has made America America is at stake," he also said. "That's why today I'm announcing my candidacy for president of the United States."
"We have to remember who we are. This is America," said the former vice president.
