 Stunning end to a decades-long career. President Biden is ending his presidential run after the panic from fellow Democrats following his miserable debate performance last month. Biden issued a one-page letter on social media saying, quote, I believe it is in the best interest of my party and the country for me to stand down. He did not give a reason why, nor did he speak publicly. He's been isolating at home with COVID. Delaware Senator Chris Coons has been co-chair of the campaign.
