Thirty minutes into the presidential debate, I’ve heard from three veteran Democratic presidential campaign officials, and all of them had the same reaction to President Biden’s performance: This is a disaster.

It wasn’t just that Biden wasn’t landing a glove on Donald Trump on the economy, the overturning of Roe v. Wade, Covid, taxes, temperament or anything else that was coming up in the questioning. It was Biden’s voice (low and weak) and facial expression (frozen, mouth open, few smirks) with answers that were rambling or vague or ended in confusion. He gave remarks about health care and abortion that didn’t make a strong point, giving Trump a chance to give lines like, “I really don’t know what he said at the end of that sentence, I don’t think he know what he said either.”

One of the Democrats said he looked scared. Another said it was an “emperor has no clothes” performance so far. The third said of the performance overall, “Don’t ask.”

Trump lied repeatedly during the debate about the pandemic, immigration and Roe v. Wade, but Biden didn’t hold him accountable for those lies in a memorable way. At times, Trump attacked Biden, but the president didn’t fight back.

Frank Luntz, the veteran focus group moderator who was holding a live focus group during the debate, wrote of their reactions so far: “The group is so bothered by Biden’s voice and appearance. But they’re getting madder and madder with Trump’s personal attacks.”

“If Trump talks less,” Luntz said, “he wins. If Biden doesn’t stop talking, he loses.”
