Americans broadly pick Kamala Harris as the winner of last week's widely watched presidential debate – yet neither she nor Donald Trump moved the needle in polling.

Ultimately, the data highlights the fact that Harris’s debate performance, while impressive, is unlikely to drastically turn the tides in her favor.

Throughout the debate, Harris mocked and needled Trump, throwing him off balance with jabs about the size of crowds at his campaign rallies. She pounced on questions about abortion and promised the country a new generation of leadership, while Trump became increasingly agitated and missed opportunities to press his case against her.
