White House officials say they have no plans to shift Mr. Biden’s messaging on economic issues, even as poll after poll shows his approval ratings in decline and voter worry over inflation swamping all other views of the economy. Their strategy remains focused on stressing the administration’s work to spread vaccinations and end the pandemic without further lockdowns, cheering the nation’s progress in economic growth and promising that Mr. Biden’s policies will bring down prices for oil, food and consumer goods.

“Every economic indicator shows an economy that is growing, that is stronger, that is creating jobs, that is putting more money in people’s pockets, and that is in part a result of President Biden’s economic agenda,” Kate Bedingfield, the White House communications director, said in an interview. “I think what you hear from the president is that he understands that when people experience a higher price at the grocery store or at the gas pump that has an impact on their budget, and so he’s doing everything in his power to bring those prices down.”

Still, there is an economic and political chasm on inflation between the administration and American voters.
