In a bid to retain support for his beleaguered presidential campaign, Joe Biden has managed to temporarily stanch the bleeding of public Democratic defections. While there are still murmurs among Democrats expressing doubts about his ability to defeat Donald Trump in the upcoming election, Biden's insistence on staying in the race has quelled concerns for now.

During a closed-door gathering of House Democrats on Tuesday, only a few members privately raised concerns about Biden's age and his chances of victory in November. This small group of dissenters included Representatives Seth Moulton of Massachusetts, Mike Quigley of Illinois, and Mark Takano of California, who had either publicly or privately called for Biden to step aside.

However, Biden did receive a small victory when longtime Representative Jerry Nadler of New York, the top Democrat on the Judiciary Committee, appeared resigned to the fact that Biden would remain as the nominee. This came after Nadler had previously called on Biden to exit the race during a private call with fellow committee leaders.

In a public letter and private phone calls to lawmakers, Biden declared that he would not be quitting the race following his disappointing debate performance last month. The majority of lawmakers in attendance at the Democratic National Committee headquarters on Tuesday agreed that Biden is the party's nominee and that it was time for Democratic officials to rally behind him.

Despite some concerns being expressed privately, there is an "overwhelming consensus that Biden has decided to stay in the race and we should unify behind him," said a House Democrat and Biden ally. Minority Leader Hakeem Jeffries of New York publicly backed Biden remaining as the nominee but did not attempt to exert pressure on opposing views during the meeting.

To discourage leaks, lawmakers were instructed to leave their phones and smart watches at the door, and Jeffries emphasized the need for confidentiality during the gathering. As a result, many members of the Democratic party were tight-lipped as they left the meeting.

While Biden and his allies work to maintain unity, some Democrats remain concerned that the president is just one gaffe or slip-up away from a political catastrophe. There is apprehension about his declining performance and the worry that the issue of age may overshadow the rest of his campaign.

Constituents back home have also been voicing their concerns about Biden's health and his ability to defeat Trump. Representative Lori Trahan of Massachusetts, who had previously supported Biden, issued a statement expressing her own concerns and the need for him to prove his capability to both her and the voters.

As the election draws near, it remains to be seen whether Biden can fully secure the support of his party and alleviate doubts surrounding his electability. The coming months will be crucial for his campaign as he seeks to convince Democrats and voters that he is the best candidate to take on President Trump in November.
