For the past three nights, I’ve watched my TV set with jitters.

On Tuesday and Wednesday, I worried that my resurgent Mets would run afoul of the Yankees. I hate watching the Mets lose to the Yankees as much as I hate any scenario in sports – or anything else for that matter.

I needn’t have worried. The Mets bludgeoned the Yankees both nights. Mr. Met’s legions triumphed over the guys with the 27-rings shirts and the bandwagoners in pinstripe shirts with the name on the back.

So I hoped to go 3-for-3 last night watching the debate between President Biden and Donald Trump. Sure, I had the same sense of dread as the other two nights. But they turned out OK, so maybe the debate would too.

Uh, no. 

You could tell when he walked onto the stage that it was going to be bad. He looked like a befuddled old man trying to find a seat on a park bench. His gait was halting. His mouth formed a circle like the one in Munch’s “The Scream.”

He painfully reminded me of my father’s final years, when a vigorous, strong man was diminished.

I would trade both those Met wins for Biden holding his own. Alas, I can’t.

Since then, I’ve had three thoughts that, even though you didn’t ask, I’m going to share.

ONE: Within five minutes of the debate’s end, I sent a campaign contribution to the Biden-Harris campaign.

I wasn’t completely sure how I felt in the moment. But like many other Democrats, I think of Joe Biden as a hero. He took on Trump at a perilous moment in 2020 and, despite the mewling of Trump and his sycophants, beat him like a drum.

And Biden has delivered a remarkable presidency. Which leads to…

TWO: History has its eyes on you, as they sing in “Hamilton.” 

Much was made of the fact that Biden kept referring to the presidential historians who rate Trump the worst president ever. And, OK, maybe he shouldn’t have dwelled on that.

But in 2074, when late-century historians evaluate Biden’s presidency, they’ll see his legislative accomplishments, his focus on economic fairness, the quality of his staff, and the humanity and decency that comes naturally to him. And they’ll put him in the pantheon of greats – in the same line as Washington, Lincoln and FDR.

Unless…

THREE: History is written by the winners. If historians in 2074 have to be certified by the Stephen K. Bannon School of Historical Revision and Correction, Biden won’t come out so well. 

The 388 million Americans of that time will hear how Biden allowed 6 billion people to illegally cross the border. Because all 7 billion of them got put on Social Security and Medicare, those programs had to be canceled. And the 8 billion terrorists who came into the country were only foiled from their nefarious plans by the wisdom of Tsar Donald I.

Even among those remaining who remember democracy in the United States, they will blame Biden for allowing Trump to get back into the White House.

How Biden looked and sounded last night are one thing. It’s what he failed to do and mention that have me shaken. The effort to ban IVF and birth control. The threat to LGBTQ rights, including the same-sex marriages of people such as my daughter and her wife. The 2025 Project, a playbook for totalitarianism.

It might have been OK if Biden just had one bad night – as many Democratic leaders are calling it – against Nikki Haley or Marco Rubio or Mitt Romney. It’s another to have it against Donald Trump.

We’d be screwed if the soldiers invading Guadalcanal in 1942 and Normandy in 1944 had a bad day. That’s how you have to look at what happened with the president last night.

I don’t know how this is all going to play out. How would the Democrats nominate another candidate?Who would they nominate? Would they pick the next in line, an apparently very unpopular Kamala Harris, or come up with a fusion ticket of Democrats and Never Trump Republicans.

I’m as scared as you are. I think I’d feel better if Joe Biden came to the realization that people who are fond of him feel the same way.
