The Democratic Party is grappling with the idea of replacing President Joe Biden as the nominee for the 2024 election following his lackluster debate performance, with discussions on potential alternatives like Vice President Kamala Harris. Concerns about the age and mental fitness of politicians like Biden and other senior figures in Congress have sparked broader debates about the need for new leadership. While some argue that Biden is the best chance against Donald Trump, others believe that a change is necessary to secure victory. The possibility of a last-minute replacement for Biden is seen as challenging and unprecedented, potentially leading to division within the party and uncertainties about alternative candidates' viability in such a short timeframe.
