In recent developments, key allies of President Joe Biden have expressed their doubts about his chances of winning the election, urging him to reconsider staying in the race. These concerns have been further fueled by the aftermath of a debate debacle late last month, where Biden struggled to stabilize his campaign. Despite efforts to repair the damage, including private meetings with Democratic senators and a forthcoming presidential news conference, lawmakers and party officials remain unconvinced.

Insiders and advisors involved in Biden's re-election campaign have openly voiced their opinions, stating that his chances of victory are now unrealistic. They believe that the ongoing questions about his cognitive abilities, lackluster fundraising efforts, declining support in polls, and the success of other Democratic candidates make it increasingly unlikely for Biden to secure the nomination.

This sentiment is not limited to external entities alone. Many within Biden's campaign and Democratic support groups share the belief that he should step aside and allow another candidate, potentially Vice President Kamala Harris, to lead the party's charge against incumbent President Donald Trump. Some have even questioned their initial support for Biden, asking who would be the best person to defeat Trump.

In response to these concerns, a Biden campaign spokesperson, TJ Ducklo, has refuted claims of internal doubt and reiterated the campaign's unwavering support for the President. However, sources behind the scenes assert that Biden's future as a candidate is uncertain, regardless of whether he withdraws from the race before November or falls to Trump on Election Day.

Following inquiries by NBC News, Biden's campaign chair, Jen O'Malley Dillon, and campaign manager, Julie Chavez Rodriguez, sent a memo to campaign staff reaffirming their belief in Biden's ability to win. They cited internal data and public polling, noting that the race remains within the margin of error in key battleground states. They specifically mentioned Georgia, Arizona, Michigan, Wisconsin, and Pennsylvania as still winnable states for the campaign.

However, despite their optimism, some Democratic insiders remain skeptical. Shifts in polling since the debate have raised alarms, with one AARP poll showing Biden trailing in Wisconsin, a state previously considered his strongest battleground. This has compounded fears that if Biden's performance continues to falter, it could negatively impact down-ballot Democratic candidates.

While Biden's campaign has begun quietly assessing Vice President Harris' viability in a head-to-head matchup against Trump in a new poll, there is a growing consensus among Democrats that Biden's inner circle has become significantly smaller and more insular. This narrowing circle reportedly consists of only family members and a few trusted advisers, which has led to concerns about his decision-making abilities.

Public calls for Biden to step aside have met mixed reactions. Some argue that such demands are counterproductive and could provoke a fightback from the President. However, others, including a Democratic lawmaker close to Biden, believe that stepping down would be the right move for both Biden and the country. While this lawmaker still holds hope for Biden's victory, they assert that his legacy would be irreparably damaged if he were to lose and drag down other Democratic candidates with him.

As the days progress, the pressure continues to mount on Joe Biden, with allies and party insiders increasingly questioning his viability as a candidate. While the ultimate decision rests with Biden himself, the growing concern over his election chances cannot be ignored.
