60% of US voters believe President Biden should "definitely" or "probably" be replaced as the Democratic candidate after his abysmal performance in a debate with contender Donald Trump, a Morning Consult survey revealed on Friday.

The poll's findings, which included 2,068 respondents, come as rumors and calls circulate regarding the replacement of Biden as the Democratic candidate.

Biden's performance has left some Democrats questioning his viability as the party's nominee, CNN reported, citing Democratic sources.

One source mentioned that it is hard to see how Biden can become the party's nominee, while another characterized him as "incoherent", according to the report on Thursday.

21% of Democratic voters believe Biden should "definitely not" be replaced, while 20% say "probably not."

When asked to choose between Biden and Trump, 45% chose Biden and 44% chose Trump. 

The presidential debate between #Biden and #Trump was enjoyable, to say the least, but considering that they represent the #UnitedStates, a fact-check was really necessary.

Morning Consult's results reveal that the president "has lost no immediate ground to Trump," although 57% of those who saw the debate thought Trump excelled over Biden. This includes 19% Democrats, 60% Independents, and 93% Republicans.

Biden campaign spokesman Seth Schuster questioned the framing of the poll data, which still shows Biden leading Trump by one point, and stated, "Joe Biden is not dropping out."

Thursday's presidential debate drew global attention and criticism, particularly aimed at Joe Biden's lackluster performance, an analysis by Politico details, with experts arguing that the implications are serious on the world stage. 

While Donald Trump maintained his typical provocative rhetoric, Biden's feebleness disappointed foreign diplomats and officials.

Concerns were voiced about whether either candidate demonstrated the vigor needed to lead a nuclear-armed superpower effectively.

International expectations had anticipated Trump's controversial statements but had hoped for a stronger showing from Biden.

"Enormous lies by Trump," one Western diplomat said. "On the other hand, at least we understood what he says. Maybe we are witnessing a turning point" for Biden.

The debate covered ongoing global issues such as conflicts in Afghanistan, the war on Gaza, and tensions with Russia, which are crucial concerns for international observers.

Neither candidate significantly advanced new policy ideas during the debate, with Trump accusing Biden of potential missteps leading to global conflicts and Biden criticizing Trump's international policies.

Writer Thomas Friedman wrote for The New York Times that he felt deep disappointment and concern following the Biden-Trump debate, advocating a drastic step from the Biden camp: to acknowledge Biden's shortcomings and have him withdraw from the race for the Democratic nomination.

He urged Democrats to initiate an open process to find a new, consensus candidate who can effectively challenge Trump in the upcoming election.

Friedman proposed a competitive selection process involving town halls, debates, and donor meetings, aiming to unite the party and present a compelling vision for America's future.
