Following a poorly received debate performance against Donald Trump, President Joe Biden faces increasing calls for his replacement from both Democratic voters and party elites. A Morning Consult poll indicates that 47% of Democratic voters and 59% of independents believe Biden should step aside, with 30% favoring Vice President Kamala Harris as his successor. Wealthy Democratic donors and party insiders express concern over Biden's age and cognitive fitness, while prominent Democrats like Bill Clinton and Barack Obama defend his record and urge continued support. The debate performance has significantly impacted perceptions of Biden's mental and physical abilities, leading to intensified discussions about the Democratic Party's strategy for the upcoming election.
