Did Joe Biden just destroy the premise of his presidential campaign? In a single moment in a Thursday night television interview, the former vice president encouraged a significant number of his supporters to abandon him. He also undercut his main argument against President Donald Trump.

Mike Memoli reports for NBC News:

Former Vice President Joe Biden, after again emphatically denying the claim of a former staffer that he sexually assaulted her nearly three decades ago, acknowledged for the first time Thursday the dilemma now facing some potential supporters in November, saying: “They should vote with their heart.”

“If they believe Tara Reade, they probably shouldn’t vote for me. I wouldn’t vote for me if I believed Tara Reade,” Biden told Lawrence O’Donnell during an extended interview Thursday on MSNBC.
