Sure, Joe Biden is pretty old: Listen, could you do what he's doing?

For months, since Joe Biden's age became the pet topic of the corporate media — you know, rather than the openly authoritarian maneuverings of the former occupant of the White House — I have said to anyone who will listen (OK, mostly to my wife, who nods agreeably) that I couldn’t do a quarter of the things that Joe Biden is doing. Honestly, not many of us could.

Not long ago on MSNBC’s “Morning Joe,” journalist Mike Barnicle defended Biden on the “age issue” in the same way. His comments came after host Joe Scarborough noted that Biden, beyond his normal duties as president, currently has multiple other full-time jobs:working to try to limit the conflict in the Middle East, supporting Ukraine’s war against Russian aggression, trying to stabilize relations with China. (His recent meeting with Xi Jinping reportedly went quite well.)

Here’s what Barnicle had to say about the media’s focus on Biden’s age:

Scarborough pointed out that leaders and diplomats around the world admire and trust Biden and say that he fully understands the issues facing their own countries. Scarborough also commented that Biden works hard as president, while Trump notoriously spent most of his days in the White House watching cable TV until noon and often continued viewing even when he bothered to show up in the Oval Office.

Trump entered the presidency with no experience in public service and left it with next to none. He did, however, leave office with two impeachments and box after box of classified documents. One recalls that Rex Tillerson, his first secretary of state, said that getting Trump to pay attention to important issues around the world was always a challenge, partly because he was likely to listen to others and “form a view that had no basis in fact.” (We all know what Tillerson really thought of Trump.)

I understand the hand-wringing about Biden’s age. Didn’t he say he would be a one-term bridge to a better, Trumpless future? (Well, Republicans haven’t given up on their angry cult leader.) Haven’t I considered Ruth Bader Ginsburg’s decision to remain on the Supreme Court? Don’t I hear Bill Maher and David Axelrod unhelpfully quailing at the polls and saying that Biden can’t win because people think he’s too old? I have, and it makes me feel deeply anxious (so I stop thinking about it and go for a walk or do some push-ups).

Still, Biden is doing a lot more than I could do, and I suspect (as Barnicle said indignantly) that he's doing a lot more than most of us could do, physically and emotionally, and he’s doing it with something we lack: a deep understanding of the deftness needed in maintaining personal relationships and the give-and-take critical to governing and diplomacy.

Biden has the experience we need in political leadership in general, especially with the Republican Party dead and gone and reduced to playacting “toughness” by elbowing House colleagues and challenging witnesses to fistfights in the Senate. Too many Republicans don’t take their oath of office seriously, and now even have to be reminded they are members of Congress. These seriously unserious people know their ideas are unpopular with the American public and thus have seriously unhinged plans for instituting minority rule permanently in any way they can.

Less than a year from now, Americans face a choice between remaining a democratic republic or morphing into a chaotic, vengeful theocracy, where millions of immigrants will be sent to holding camps before being deported (that’s the stated plan) and where women and people of color and LGBTQ folks and political “enemies” and journalists and authors and critics are targeted by those in power. For all their endless talk about the First Amendment, the MAGA insurrectionist party wants to turn it on its head, by instituting a national “religion” (Christian in name only) and silencing dissent.

Would it be ideal to have someone younger than 80? Sure it would. But that’s not reality this time around. And that imaginary 45-year-old wouldn't have the extensive institutional and foreign policy experience that Joe Biden has. The Democratic Party has quite a few truly worthy (and perhaps even charismatic) future candidates for the highest office waiting in the wings, gaining more experience in governing and serving all the citizens in their districts or states, not just the ones who voted for them.

But those candidates will need a liberal democracy in place (i.e., basic rule of law, support for voting rights, willingness to compromise on policies and acceptance of the peaceful transfer of power) for us to find out what they can do to move us forward.

If you think 80 is really old — well, in some cases it is. People sometimes die much younger than that. In the two months since I retired, I’ve lost two close friends. But let’s list just a few older people who are still out there killing it: Paul McCartney is touring again and puts on vigorous three-hour concerts (without breaks). He turned 81 in June. Mick Jagger is still doing that chicken-strut thing he learned from Tina Turner, and celebrated his 80th birthday in July. At 97, Mel Brooks is sharper (and a lot funnier) than you or me. So is the amazing Norman Lear, at 101. Many notable scientists, philosophers, poets, artists and people in other demanding fields function at a high level, mentally and physically, deep into their lives.

Moreover, emotional well-being tends to increase in old age, as personal ambitions drop away and we allow ourselves the time to just be. (These findings do not apply to people who never grow up, by the way.) Biden stays active, eats a good diet, has social intelligence and awareness of others’ needs, has varied interests and solves complex problems daily — those, it seems, are the habits and characteristics of "super agers." He is buoyed by a loving wife and family, because he’s earned that love. (The Beatles would approve.)

No matter how any of us may feel about Biden going for a second term at his age, it is beyond my comprehension that anyone could consider Trump, who is only a few years younger, as being more mentally or physically competent. According to his niece Mary Trump and others who know him well, has not been mentally fit for most of his life.

Physically, as a young man Trump claimed he was not fit enough to serve his country, and, by all accounts, his diet continues to be a disaster zone of highly processed food and well-done steaks served with ketchup, sometimes tossed against the wall (speaking once again to his mental state, which seems to be characterized by endless, irrational resentment).

Does Trump have any interest in or curiosity about anything beyond himself (except for a few of his favorite authoritarian leaders)? Has he ever solved a complex problem for the benefit of anyone but himself? He’s teased them endlessly but has never delivered — think those multiple, embarrassing “Infrastructure Weeks”; think “I will get it all done” to bring peace to the Middle East, fobbed off on his embarrassing son-in-law.

Trump has made it crystal clear over many years that he is vengeful and only out for himself. He now threatens those he wants to “root out” like “vermin,” jutting out his chin like his favorite historical Italian dictator and talking like his favorite German one. He also likes to fantasize that he’s a superhero.

I suspect that if it weren't that guy the Republicans seemed determined to put up again, Biden would have determined it was safe to step aside. But it is that guy, who now has two impeachments, 91 felony indictments in four different jurisdictions, findings of liability for sexual assault and business fraud, and a history of telling lies every time he opens his mouth, including persistent whoppers about the 2020 election and about being good at business.

Liberals and progressives, broadly speaking, tend to be people who believe in reality, in facts. Whether we're delighted about this or not, Joe Biden is running for president again. His leadership, whether you agree with every decision or not, can help us extend the American experiment and bolster democracy, as well as fight for more ways to share our nation’s prosperity and protect its cultural heritage.

The other choice will be a man who is chronologically almost as old and who seems to live in an entirely imaginary version of America in a previous era. He is mentally and emotionally unstable, to say the least, and has no interest and no ability to help anyone other than himself. Oh, and he intends to be a dictator and get revenge on his perceived enemies.

If we lose our democracy because voters tie themselves in knots about Joe Biden's age. that will go down as ageism for the ages.
