"Mr. Trump fares especially well among those who believe that the political and economic systems ought to be torn down, a group that represents about 15 percent..."

"... of registered voters. He leads among these anti-system voters by 32 points, and the tear-it-down voters are especially likely to have defected from the president. In contrast, Mr. Biden retains nearly all of his 2020 supporters who believe only minor changes are necessary. These change voters are not necessarily demanding a more ideologically progressive agenda.... Instead, Mr. Biden’s losses are concentrated among moderate and conservative Democratic-leaning voters, who nonetheless think that the system needs major changes or to be torn down altogether."

From "Trump Leads in 5 Key States, as Young and Nonwhite Voters Express Discontent With Biden/A new set of Times/Siena polls, including one with The Philadelphia Inquirer, reveal an erosion of support for the president among young and nonwhite voters upset about the economy and Gaza" (NYT)(free access link/useful charts and details).

Also: "Mr. Trump and Mr. Biden are essentially tied among 18-to-29-year-olds and Hispanic voters, even though each group gave Mr. Biden more than 60 percent of their vote in 2020. Mr. Trump also wins more than 20 percent of Black voters — a tally that would be the highest level of Black support for any Republican presidential candidate since the enactment of the Civil Rights Act of 1964. The polls suggest that Mr. Trump’s strength among young and nonwhite voters has at least temporarily upended the electoral map, with Mr. Trump surging to a significant lead in Arizona, Georgia and Nevada — relatively diverse Sun Belt states where Black and Hispanic voters propelled Mr. Biden to signature victories in the 2020 election."
