While Bret Stephens accurately identifies specific instances where Biden's administration made incorrect predictions about immigration, Afghanistan, and inflation, and raises valid concerns about transparency regarding his health and family matters, his critique is weakened somewhat by depending on a questionable analogy and an appeal to motive.

1. questionable analogy • The author is quick to compare Biden's government spending agenda to that of Lyndon Johnson: ​

The centrist voters who put Biden in the White House saw him as a safe and consoling pair of hands. Instead, he sought to govern as the second coming of Lyndon Johnson, with spending proposals amounting to $7.5 trillion -- nearly twice what we spent to win World War II, adjusted for inflation.

This creates a dubious comparison between Biden and LBJ's presidencies, ignoring vast differences in historical context, economic conditions, political environment, and the nature of their respective policy initiatives: ​

• Different contexts: Biden and Johnson governed in vastly different historical contexts, facing different economic challenges and political landscapes. ​
• Different motivations: Stephen's language implies that Biden's spending is driven by a desire to emulate Johnson's approach to governance, but it could be motivated by entirely different factors. ​
• Oversimplification: The comparison ignores the nuances of both Biden's and Johnson's policies and reduces their complexities to a single, simplistic analogy.

2. appeal to motive • Stephens presumes there to be a self-interested motive behind Biden's senior staff not coming forward with concerns about his cognitive decline:

Perhaps the president didn't notice his own decline, so the deception might not have been his. But his entire senior staff must have noticed, and, as The [Wall Street] Journal reported, they took advantage of it to enhance their own power.

This dismisses staff actions by attributing them solely to self-serving motives while ignoring other plausible explanations like a sense of loyalty, psychological denial, concern for institutional stability, or genuine belief in his capability. This logical leap is material to the main title of Stephens' essay, because it means that messaging about Biden's fitness for office might not have been an outright "deception."
