This Debate, We Could Hear Biden Speak. There His Troubles Began.

The CNN presidential debate kept the volume down, for a change. That didn’t make it more intelligible.

With the plans for the 2024 presidential debates, President Biden’s campaign appeared to get much of what it wanted. It got its preferred timeline, with Thursday night’s debate in Atlanta far earlier on the calendar than usual. It got the live audience removed. It got, above all, an agreement to mute the microphone on the candidate who wasn’t speaking, to avoid the cross-talk that made his first 2020 debate with Donald J. Trump a cacophonous mess.

After Thursday night, Mr. Biden — and his party — might have wanted the cross-talk back.

The changes that CNN instituted staved off the shouting matches and the competitive cheering that have marked past debates. But they could not prevent Mr. Biden from starting his rushed opening remarks in a papery rasp that, before the debate was over, his campaign was stressing to reporters was the result of a cold. It did not keep him from getting lost in the corn maze of his sentences, answer after answer.

And it did not keep him from finishing an argument on tax reform and health care with a spiral that was surely saved instantly to the hard drives of Republican campaign operatives: “Making sure that we’re able to make every single solitary person eligible for what I’ve been able to do with, the, uh, with the Covid, excuse me, with, um, dealing with, everything we had to do with, uh … look … if — we finally beat Medicare.”

There was no interruption. Mr. Biden came across loud and unclear.

You can at least credit Mr. Biden for one accomplishment: For perhaps the first time since Mr. Trump announced for president nine years ago, he managed to hold a debate in which Mr. Trump’s performance was not the biggest news afterward.
