One of the saddest moments of my life was the day I felt compelled to tell my father that he should give up his car and stop driving. He resisted, but only briefly. It was an example of the kind of man my father was.

And it is an example for us today when we consider the peril our republic faces with President Biden clinging to his reelection bid.

We all know the liberating feeling we had when we got our first driver’s license. The opposite feeling comes when it is time to turn it in. In my dad’s case, the problem was diminished eyesight. A resilient man, he had learned to live with many handicaps, including loss of a leg and use of an arm. He told me of a trick he successfully used at traffic intersections to compensate for his difficulty discerning red lights from green: He waited for other cars to move.

Okay, I said, how will you feel if you end up hurting someone? That was all it took. He sold his car.

Such a moment has come now to Joseph Biden. The chances of him winning in November are virtually non-existent. Yet, he continues to make statements that defy reason in order to keep the keys to the White House.

The president’s performance in his recent debate with Donald Trump was a shock to anyone with eyes and ears. His handlers have limited his unscripted interactions with journalists for precisely this reason. Yet he and his staff insist he is as intellectually vigorous as ever and trot out ludicrous excuses for why he stumbled. One of the excuses, jetlag from recent trips abroad, showed the opposite of what was intended – that is, that it takes the president 11 days to recover from travel.

They, argue that he is the best person to beat Donald Trump in November. After all, they say, he is the only one who has bested Trump at the ballot box. On close inspection, however, the statement is nearly meaningless. Trump has only been in two election races, and the one he won was fluky, to say the least. His opponent, Hillary Clinton, ran a poor campaign – and still won the popular vote. Several Democrats have a better chance than Biden of beating Trump this time round.

It is sad to hear Biden claim he is intellectually up to the job at the same time he says the polls are not all that bad. As the RealClearPolitics Poll Average shows, Trump is decidedly ahead of Biden. Moreover, Biden probably needs around 52% of the popular vote to win, given how the Electoral College functions.

It might be comforting to think that there is still time to turn things around. But anyone can see that Biden is losing voters, not gaining them. The best that can be said is that the battle lines have been fixed in Trump’s favor. Biden has been lagging for months and that shows no signs of changing.

It is understandable that the president seeks supportive advice from staff as well as his wife, Jill, and his son, Hunter Biden. We all want reassurance. But we also need to seek out those who will give us a point of view that we do not want to hear.

Contrary to what Biden is claiming, the elites are not out to get him. Taking on the mantle of victimhood only makes Biden seem unhinged – and more like Trump. Polls show that nearly three-quarters of Americans think Biden is not fit to serve, mainly as a result of the impacts of aging.

The issue is not Biden’s age, per se. Donald Trump, 78, is not much younger than the president. The issue is that in recent years Biden’s acuity and physical presence have shown noticeable decline. Whatever one wants to say about Trump, he is vigorous.

One of the great strengths of the Democrats in recent years is that they have a much better record of dealing with reality than Republicans, who have blindly followed a leader whose attachment to the truth is tenuous.

Party leaders now face a test of their credibility.

Some Democratic lawmakers have begun to speak out, urging the president to end his campaign. But more – many more – must step up. They must do what they have said the opposition has failed to do: speak truth to power. Otherwise, an important distinction between the parties disappears along with the possibility of winning the November election.  

Like my father, Biden has faced personal hardship and prevailed. That courage is a sign of greatness. I stand with those who believe Biden has many accomplishments and should be proud of his presidency.

But this moment may be his greatest test. True greatness lies in facing facts, not in wishful thinking, and in thinking of the consequences for others, not oneself.

Biden needs to turn in the keys and let the party make a credible fight for the country. That’s what my father, a hardworking American who never pitied himself, would have done. I loved him for it.
