Concerns are rising within the Democratic Party regarding President Joe Biden's candidacy, with some senior figures suggesting he should consider stepping aside due to worries about his age and performance. Former President Barack Obama has reportedly privately expressed doubts about Biden's ability to win against Republican nominee Donald Trump. Calls for Biden to withdraw have emerged following a poor debate showing and ongoing challenges. Despite the pressure, Biden maintains his campaign, while some Democrats see Vice President Kamala Harris as a potential alternative with the ability to shake up the race. The recent assassination attempt on Republican nominee Donald Trump has shifted focus away from efforts to replace Biden, temporarily pausing the debate within the Democratic Party.
