Following a shaky debate performance, concerns about President Joe Biden's mental fitness have surged, with a CBS/YouGov poll indicating 72% of Americans, including 46% of Democrats, believe he is unfit to serve. Biden, battling a cold during the debate, faced criticism for his age and performance, sparking speculation about his potential replacement. Despite this, influential Democrats like Rep. James Clyburn support Biden's continued candidacy, and Biden is set to meet with his family to discuss his political future. Historian Allan Lichtman argues that replacing Biden could jeopardize the Democrats' 2024 election chances. However, polls reveal no clear alternative Democratic candidate who would perform better against Donald Trump.
