CNN’s chief data analyst Harry Enten on Friday said President Donald Trump’s cratering support among independents is the “biggest danger” he’s facing in his second term.

“It does not appear that there is a bottom to which Donald’s support can’t fall to,” Enten told CNN’s John Berman.

Enten — who recently covered how Trump has fared better with Republicans despite the fallout from the Jeffrey Epstein files — turned to how the president’s net approval rating (percent approval minus percent disapproval) with the key voting demographic dropped from an average of -3 in January to -29 in July.

His net approval rating with independents, per Gallup, also fell from -2 in January to -35 this month.

“If you’re not winning among independents, you’re probably not winning overall,” Enten said.
