CNN’s chief data analyst Harry Enten on Tuesday argued that Kamala Harris is losing steam with Democrats as the former veep continues to spill on her 2024 campaign while promoting her new book “107 Days.” (Watch his analysis below.)

“I would just say that if you want a messenger to go against Donald Trump, you could do far better as Democrats than Kamala Harris,” said Enten in a segment with CNN’s Sara Sidner.

Enten pointed to the former vice president’s net favorable rating (percent of those in favor minus percent not of those not in favor), which has dropped from -5 in October 2024 to -13 this month, according to Fox News polling.

Among independents, that figure is at -37, per the poll.

“If you can’t win independents, you can’t win the election,” Enten said.
