As Joe Biden prepares to address the Democratic National Convention in Chicago, he faces the reality of stepping aside from his presidential campaign amidst pressures from party leaders regarding his age and debate performance. Despite a record of significant accomplishments, Biden's decision to withdraw reflects a broader consensus among Democrats that an 81-year-old candidate may struggle to defeat Donald Trump again. The support he once enjoyed eroded following a disastrous debate, leading to his eventual concession, which was met with understanding and praise from his party. His vice president, Kamala Harris, now takes center stage as the nominee, marking a new chapter in the Democratic leadership. Friends and aides acknowledge the ups and downs of Biden's journey, emphasizing his resilience and the lessons of perseverance instilled by his parents. As he navigates this transition, Biden aims to demonstrate the distinction between stepping aside and quitting.
