Biden’s News Conference Answered Many Questions. But Not the Big One.

There were many questions at President Biden’s nearly hourlong news conference on Thursday night — questions about Gaza, Ukraine, the campaign, his health, his record.

But at its heart there was only one question: Could he do it?

That is, could Mr. Biden, who stunned viewers and his party and George Clooney with a doddering performance at the first presidential debate two weeks ago, stand and deliver? Could he be coherent? Could he dispel the talk of age and frailty and decline? Could he beat the doubters who want him to step down from the ticket? Could he look like a winner?

On a national TV stage, Mr. Biden answered the individual questions, often comfortably, sometimes defensively, with depth and engagement and flashes of passion. As for the uber-question, the answer was incomplete. He was not the uncomfortable, lost presence of the debate, but he didn’t erase the memory of that version of himself either. He came across as the president he wants to be, but not necessarily the candidate his critics have said he needs to be.

Presidential news conferences are rarely must-see TV. But the stakes — heightened by reports that some Democrats were waiting for it before weighing in on whether Mr. Biden should remain the nominee — gave this one the air of a test, if not a last stand.

The telecast had the daredevil feel of a live walk through a minefield. The first false step came before the news conference proper, at remarks after the afternoon’s NATO meeting, when Mr. Biden introduced President Volodymyr Zelensky of Ukraine: “Ladies and gentlemen, President Putin.”

The president caught himself and recovered. “I’m better,” Mr. Zelensky joked; “You’re a hell of a lot better,” Mr. Biden said. The audience laughed. Anybody can mix up a name once.
