New polling showing a sharp drop in voters' confidence in President Biden's fitness for office stunned one data analyst on Monday.

"If you look at the polling now compared to what it was pre-debate and compare it to what it was four years ago, it‘s just not even on the same planet," CNN reporter Harry Enten reacted on the network.

Biden faces an uphill battle to regain voters' confidence after last Thursday's shaky debate performance, as a new poll from CBS News shows a large majority of voters now doubt his mental fitness to be president.

According to that poll, 72% of voters think Biden is mentally unfit to serve. But four years ago, just 36% of voters thought Biden was too old to be president, Enten said.

"Four years ago, voters for the most part thought Joe Biden was with it. He could handle the job as president. You look at those numbers now, the fact is, voters do not even see them on the same planet. They don‘t think Biden‘s with it. They do not believe he has the mental fitness to be president," he said.

"And I have to be honest with you, I don‘t know how he wins with the numbers that we see right now. There is no precedent for the numbers that we‘re seeing right now for someone running for president, letting alone getting a nomination," Enten continued.
