CNN data reporter Harry Enten spotted a major warning sign for President Donald Trump in the latest polling data as voters give him low marks in the one area that used to be his greatest strength: the economy.

“I honestly never thought I’d see the day in which Donald Trump would be polling so poor on the economy, but that day is here,” Enten said on Thursday.

Enten said four new polls “tell a consistent story” about Trump: His approval ratings, which were in positive territory last month as he began his second term in office, have now completely reversed.

“Trump is on the negative side of the ledger,” Enten said. “His net approval is negative. He is underwater like ‘The Little Mermaid.’”

All four of the new polls released Thursday show him with a negative net approval rating, he pointed out, making it Trump’s “worst day of polling” since he took office.

But it’s his numbers on the economy that really stand out.

“This was one of Donald Trump’s great strengths,” Enten said. “Now it’s one of his great weaknesses.”

Enten said that in February 2017, at a similar point during Trump’s first term in office, an Ipsos poll had him up by 16 points on the economy. Now, he said, that same poll has him down by 8.

He said it comes down to one core issue ― and it’s the same one that bedeviled Trump’s predecessor.

“As I said last week, inflation ate the Joe Biden presidency alive, and right now it is very much the case that Donald Trump is in danger of inflation eating his presidency alive, because his net approval ratings on the economy are underwater.”
