Why Young Voters Are Changing Their Minds About Kamala Harris

The young voters who said they were less likely to vote for Ms. Harris after the speech said they felt it lacked substance or included stands they disagreed with. One of them, Pierce, a 26-year-old who works in sales in North Carolina and didn’t vote in 2020, said she lacked substance on policy and sounded “rehearsed,” including on the war in Gaza. Mark, a 24-year-old chef from California who voted for Mr. Biden in 2020, said he liked her condemnation of Jan. 6 and her attacks on Mr. Trump but said that Israel and Gaza left him troubled about Ms. Harris.
