Throughout the initial months of 2024, numerous mainstream media outlets staunchly defended President Biden's cognitive abilities, dismissing videos suggesting decline as fabricated. This narrative crumbled after his subpar debate performance, leading to a significant shift in media coverage.

The release of Special Counsel Robert Hur's report, which described Biden as having a "poor memory," sparked varied reactions. While some outlets adopted a "Republicans pounce" narrative, others downplayed the report's findings. Notably, some commentators focused on Biden's ability to "ride a bike" as evidence of his fitness.

Following the report, Biden's press conference, where he mistakenly referred to the Egyptian president as the "president of Mexico," and his combative exchange with a CNN reporter about his age further fueled concerns.

A June Wall Street Journal article detailing interviews with individuals who perceived a decline in Biden's abilities was largely dismissed by mainstream media, with some labeling it a "Trump hit piece." This dismissal echoed earlier narratives that concerns about Biden's fitness were merely Republican talking points.

The White House's attempts to discredit videos showing Biden appearing disoriented or confused as "cheap fakes" were further challenged by his debate performance. Biden's struggles to articulate his message and maintain focus during the debate prompted even his media allies to question his fitness for office, with some calling for him to withdraw from the race.

After the debate, explanations for Biden's performance ranged from a cold and jet lag to being distracted by Trump. Ultimately, the narrative settled on a "bad night." Biden subsequently dropped out of the race, endorsing Kamala Harris, who secured the nomination and ultimately lost to Trump in the general election.

The same media outlets that had previously urged Biden to withdraw now praised his decision, highlighting his "selfless devotion" to the country. This shift in tone underscored the evolving media narrative surrounding Biden's fitness for office.

This evolving narrative continued even after Biden left office. A late 2024 New York Times piece acknowledged Biden's declining physical and mental state, reflecting a stark contrast to the earlier defenses of his fitness.
