CNN chief data analyst Harry Enten said on Monday he usually compares President Donald Trump’s underwater net approval ratings to Olympic divers such as Greg Louganis.

But in the latest polls, Trump has taken such a deep plunge that Enten said he is at a loss.

“I don’t really know who to even compare Donald Trump to because he’s just so low,” Enten said. “And he’s so low with the center of the electorate.”

Enten pointed out that Trump is now 27 percentage points underwater among independents, according to one new poll, compared to 17 below at this point in his first term.

“When you lose the center of the electorate, you lose the American people,” Enten said.

He warned Trump that this could spell disaster for Republicans in November’s midterm elections, when control of the House and possibly even the Senate ― both currently under GOP control ― will be at stake.

“I don’t understand how this works out well for the president of the United States,” he said. “When you are 27 points below water, underwater, with the center of the electorate, with independents, you lose. Your party loses.”

The latest numbers also led Enten to a key question about Trump’s approval ratings.

“There’s this question that folks keep asking: Where is the floor for Donald Trump?” he said. “And I’m not sure there is a floor, because if there is one, Donald Trump, at least in term number two, has just fallen through it to another low level.”

Enten displayed the latest results from four different pollsters showing Trump ranging from 19 points underwater all the way to 26 points below water in his net approval ratings.

Trump, he said, is now 22 points underwater on average ― well beneath the -17 from the same point in his first term, and the -13 that Joe Biden had at this point in his presidency.

“So the bottom line is this: Donald Trump is setting new records for himself in term number two,” he said. “And he’s doing worse than Joe Biden, which is, of course the comparison that Donald Trump does not want to be, because we all know what happened to Joe Biden.”

Biden’s unpopularity cost his party control of the House in the 2022 midterm elections, and he eventually had to drop his reelection bid.
