Biden's gaffes are likely an extension of his stutter - which he has had most his life.

96. What Joe Biden Can't Bring Himself to Say

I was a stutter until about 4th grade. I find these attacks on Biden to be sad. This article about Joe's stuttering really hit home with me. The discussion of the movie The King's Speech was very moving for me.

In Biden’s office, the first time I bring up his current stuttering, he asks me whether I’ve seen The King’s Speech. He speaks almost mystically about the award-winning 2010 film. “When King George VI, when he stood up in 1939, everyone knew he stuttered, and they knew what courage it took for him to stand up at that stadium and try to speak—and it gave them courage … I could feel that. It was that sinking feeling, like—oh my God, I remember how you felt. You feel like, I don’t know … almost like you’re being sucked into a black hole.”

Presidential candidates usually don’t speak about their bleakest moments, certainly not this viscerally. It resembles the way Biden writes in his memoir about the aftermath of the 1972 car accident that killed his first wife and young daughter and critically injured his two sons, Beau and Hunter: “I could not speak, only felt this hollow core grow in my chest, like I was going to be sucked inside a black hole.”

A few weeks later, I ask Jill Biden what she remembers about sitting next to her husband during the movie. “It was one of those moments in a marriage where you just sort of understand without words being spoken,” she says.

As he watched The King’s Speech, Biden accurately guessed that the screenwriter, David Seidler, was a stutterer. “He showed me a copy of a speech they found in an attic that the king had actually used, where he marks his—it’s exactly what I do!” Biden tells me, his voice lifting. “My staff, when I have them put something on a prompter—I wish I had something to show you.”

I agree with Joe that it would be difficult for trump to use Joe's stutter against him

In Biden’s office, as my time is about to run out, I bring up the fact that Trump crudely mocked a disabled New York Times reporter during the 2016 campaign. “So far, he’s called you ‘Sleepy Joe.’ Is ‘St-St-St-Stuttering Joe’ next?”

“I don’t think so,” Biden says, “because if you ask the polls ‘Does Biden stutter? Has he ever stuttered?,’ you’d have 80 to 95 percent of people say no.” If Trump goes there, Biden adds, “it’ll just expose him for what he is.”

I ask Biden something else we’ve been circling: whether he worries that people would pity him if they thought he still stuttered.

He scratches his chin, his fingers trembling slightly. “Well, I guess, um, it’s kind of hard to pity a vice president. It’s kind of hard to pity a senator who’s gotten six zillion awards. It’s kind of hard to pity someone who has had, you know, a decent family. I-I-I-I don’t think if, now, if someone sits and says, ‘Well, you know, the kid, when he was a stutterer, he must have been really basically stupid,’ I-I-I don’t think it’s hard to—I’ve never thought of that. I mean, there’s nobody in the last, I don’t know, 55 years, has ever said anything like that to me.”

This is an issue that I have strong feelings about.
