The Democrats onstage saw themselves as morally courageous. American voters, it turned out, saw a group of politicians hopelessly out of touch.
Standing side by side at a primary debate in June 2019, 10 of the party’s candidates for president were asked to raise their hand if they wanted to decriminalize illegal border crossings. Only one of them held still.
Six years later, the party remains haunted by that tableau. It stands both as a vivid demonstration of a leftward policy shift on immigration that many prominent Democratic lawmakers and strategists now say they deeply regret, and as a marker of how sharply the country was moving in the other direction.
Last year, 55 percent of Americans told Gallup that they supported a decrease in immigration, nearly twice as many as in 2020, and the first time since 2005 that a majority had said so. The embrace of a more punitive approach to illegal immigration includes not only white voters but also working-class Latinos, whose support Democrats had long courted with liberal border policies.
“When you have the most Latino district in the country outside of Puerto Rico vote for Trump, that should be a wake-up call for the Democratic Party,” said Representative Vicente Gonzalez of Texas, who saw Mr. Trump win every county in his district along the border with Mexico. “This is a Democratic district that’s been blue for over a century.”
