The exact moment the Kamala Harris campaign turned, according to pollster Frank Luntz

Pollster Frank Luntz told CNN on Wednesday the moment he believes Democrat presidential nominee Kamala Harris lost the upcoming election.

Luntz said that Harris was doing great as a candidate until she started attacking former Presient Donald Trump.

"She had the best 60 days of any presidential candidate in modern history," Luntz said.

"And then the moment she turned anti-Trump and focused on him and said, 'don't vote for me, vote against him' -- that's when everything froze," he added.

On Thursday, Luntz told NewsNation that uncommitted voters will likely determine the next president.

He said that he does not, at this point, know who will win, but added that the election is "not a game anymore."
