Many Trump supporters have said they still back the president, despite feeling the pinch themselves.
John Mohring, 60, of Kenosha, Wisconsin, has backed Trump since 2016, though rising prices worry him.
Mr Mohring, who works in construction and has lived alone since his wife passed away three years ago, said grocery prices started rising before Trump returned to the White House “and it doesn’t seem like it’s going down”.
He now typically spends $100 on groceries just for himself, even when avoiding buying meat and sticking with cheaper items.
Still, Mr Mohring said he backed the Trump administration’s sweeping tariffs on imported goods and his border policies.
“I’m giving him the benefit of the doubt,” Mr Mohring added.
Brad Smith, a corn and soybean farmer in north-western Illinois, was hurt earlier this year when China, previously a major buyer of US soybeans, froze its purchases amid economic friction with Washington.
But the market, he said, had been gradually recovering since late October, when the two countries reached a trade agreement and China resumed some purchases.
Trump on Monday also announced a $12bn aid package for US farmers.
Mr Smith said he still believed in Trump’s plans for the economy, despite being personally getting caught in the cross fire.
“There’s probably bigger things at play other than just the soybean and corn market,” Mr Smith said.
“The whole America First idea is good.”
