In all the English language, there’s hardly a string of five words more worthy of a spit take than this particular American president saying, “My word as a Biden.” It’s akin to Bill Clinton saying, “My word as a faithful husband” — which, of course, he never says.

But there he was Sunday, ol’ Scranton Joe saying just that: “My word as a Biden.” And he put it in front of this: “I’ve never been more optimistic about America’s future than I am today.”

The man is certifiably non compos mentis.

Where to start? With the pathological nature of Joe Biden’s penchant for lying, or with his stunning cluelessness as to the wreckage he’s wrought?

Let’s begin with the former, which includes big lies and little ones, old lies and new ones. Indeed, we can learn a lot about Biden when we consider that two of his most egregious falsehoods involve the death of family members. Biden has claimed on multiple occasions that his son Beau “lost his life in Iraq.” But the truth is that his son died of brain cancer in 2015 at Walter Reed Medical Center in Bethesda, Maryland, many years after he’d left Iraq. Why Joe Biden insists on dishonoring his son’s memory in order to steal a Gold Star is anyone’s guess.

Then there’s the one in which he repeatedly and falsely blamed the death of his first wife and daughter in a car wreck on a truck driver. This man, this trucker, was a citizen and a father. Yet Biden said he “drank his lunch.” The truth, according to the police report, was that the truck driver hadn’t been drinking and wasn’t even at fault — that, in fact, Mrs. Biden “drove into the path” of the tractor-trailer.

It’s impossible to cram Biden’s biggest whoppers into a standard paragraph, but here’s a sampler of the lies he’s told in an effort to claim identity in one constituent group or another: He said he was “appointed” to the U.S. Naval Academy. He said he was arrested in South Africa while trying to see Nelson Mandela. He said he was arrested during the Civil Rights movement of the 1960s. And he said he used to drive an 18-wheeler for a living. In addition, Biden has claimed to have visited the Tree of Life synagogue in Pittsburgh after a 2018 massacre there, claimed to have been raised by Puerto Ricans, claimed to have hit a towering home run in a congressional baseball game, and claimed gas prices were above $5 when he took office. Lies, lies, and more lies.

The dude makes Walter Mitty seem like Walter Cronkite.

Then there’s his abject failure as the head of our government. As The Daily Signal’s Jarrett Stepman notes, the average American family has lost $7,100 in purchasing power to inflation during the Biden era; we’ve seen our national debt explode to $31 trillion, which amounts to more than $94,000 for every American man, woman, and child; and we’ve witnessed a premeditated border catastrophe in which five million mostly unskilled illegal immigrants have poured into our country. On top of this, we’ve seen the Biden administration implement one of the president’s 2021 executive orders to devastating effect — namely, his order to establish a woke administrative state via a “government-wide initiative to advance diversity, equity, inclusion, and accessibility in all parts of the federal workforce.”

Perhaps most telling of all, though, is what we learned just yesterday in a new Gallup poll. As it turns out, more Americans — 21% of them — name the government as the nation’s top problem than any other issue. That’s more than inflation, more than unchecked illegal immigration, more than violent crime, more than wokeness, more than anything.

And who is it that heads this broken, ineffective, unsatisfactory government of ours? That’s right: Joe Biden.

As for optimism, well, Ole Joe doesn’t have much company there, either, as 71% of Americans think the country’s on the wrong track.

But remember: We have his word as a Biden. His word. As a Biden.
