Washington Post columnist Jennifer Rubin responded to a biased article in the Wall Street Journal that derided Biden’s fitness for the Presidency. Its primary sources: House Speaker Mike Johnson and former House Speaker Kevin McCarthy, both Trump lackeys.

Rubin wrote:

A president’s gait, verbal tics and minor recall errors have virtually nothing to do with the job of being president. The White House occupant is not a “Jeopardy!” contestant, a stand-up comic, a talk-show host or guest; the president is the head of the executive branch and commander in chief.

The job of being president is executive management, something with which political reporters (as opposed to business reporters) have virtually no expertise. We should be asking whether a candidate can absorb necessary details, make good personnel decisions, reach sound conclusions, evaluate risk and consider the consequences of actions. Can the president separate personal interests from the interests of the nation, of allies or even the planet? That is what the president does, day after day.

And we do not need to be armchair psychiatrists to evaluate that sort of presidential fitness. As I have written, Trump’s closest colleagues tell us that he is willfully ignorant, cannot grasp basic concepts, cannot absorb written material. As for his hiring decisions, by his own admission, he has hired a slew of dumb or incompetent people. He gloms on to ridiculous quack theories, and he channels the ideas and rhetoric of America’s enemies and of historical villains.

Trump cannot keep national secrets — or understand they are not “his.” He is incapable of grasping the values and ethos of military service. Because he is so susceptible to flattery and so thin-skinned, he cannot tell friend from foe. And as his former national security adviser John Bolton put it, “Trump really cares only about retribution for himself, and it will consume much of a second term.”

Part and parcel of good decision-making is impulse control. If one cannot refrain from lashing out in anger at allies, spilling secrets to U.S. enemies, or launching personal attacks and threats against fellow Americans (in defiance of court orders, no less), one cannot be entrusted with the immense responsibilities of the presidency. (There might also be something seriously wrong with you, but that is beside the point.)

Moreover, we know how Trump’s decision-making turned out. He downplayed the coronavirus, and hundreds of thousands of Americans died unnecessarily. He concocted the “big lie” about the 2020 election and, unable to admit losing, incited a riot at the U.S. Capitol. He didn’t want to reveal embarrassing sexual impropriety, so he broke the law in New York — 34 times.

You don’t need to make a specific medical diagnosis to see that the essential aspects of the presidency — judgment, reading comprehension, discretion, unselfish decision-making, appreciation for military sacrifice — are utterly beyond Trump.

At the most basic level, Biden, while three years older, can discern friend from foe, reveres the military, understands the value of alliances, generally hires capable advisers, puts together complex legislative deals and exhibits inexhaustible empathy for others’ suffering. He complies with the legal process (e.g., sitting down with special counsel Robert K. Hur), follows Supreme Court decisions (and then explores alternatives, as he did on student debt) and engages in successful international diplomacy. He talks in depth about policy.

It’s reasonable to conclude that, with age, Biden has gained immense experience, formed relationships and absorbed data that helps guide his current decision-making. Should we care that he walks more stiffly than he did 10 years ago? (FDR served 12 years in a wheelchair.)

In sum, the measure of a president — regardless of that officeholder’s level of spryness or eloquence — is the capacity to perform a singularly important job: making good decisions on behalf of others in keeping with our laws and national values. No reasonable person would conclude, based on all available evidence, that Trump can do so; no fair person would conclude that Biden’s age impedes him from doing so.
