Former Vice President Joseph R. Biden Jr. announced Thursday that he would seek the Democratic nomination to challenge President Trump in 2020, marshaling his experience and global stature in a bid to lead a party increasingly defined by a younger generation that might be skeptical of his age and ideological moderation.
Mr. Biden, 76, is set to offer himself as a levelheaded leader for a country wracked by political conflict, a rationale he believes could attract a broad cross-section of voters who want to move on from Mr. Trump.
In a three-and-a-half minute video laying out his reasons for running, Mr. Biden chose not to talk about policy issues or his biography but instead began by recalling the white supremacist march through Charlottesville, Va., in 2017 and a counterprotest, and Mr. Trump’s comment that there were “very fine people on both sides.” In that moment, Mr. Biden said, “I knew the threat to our nation was unlike any I’d ever seen in my lifetime.”
“We are in the battle for the soul of this nation,” Mr. Biden said. “I believe history will look back on four years of this president and all he embraces as an aberrant moment in time. But if we give Donald Trump eight years in the White House, he will forever and fundamentally alter the character of this nation, who we are, and I cannot stand by and watch that happen.”
