The states that would get hit hardest by Donald Trump’s proposed tariffs are Republican strongholds or ones that could determine the election’s outcome, a new analysis found.
The GOP presidential candidate has proposed tariffs of 60% on Chinese imports and 10% to 20% on goods imported from all other nations.
The tariffs would take the biggest chunk off the gross domestic products, or GDPs, of Indiana, Kentucky, Tennessee, and Mississippi — all reliably GOP states in presidential elections, according to a new report from the Tax Policy Center. Illinois, Wisconsin, and Michigan followed. The latter two are considered swing states.
“Tariffs, they do matter,” said Robert McClelland, a senior fellow at the Urban-Brookings Tax Policy Center and one of the researchers. “It could definitely affect economies, it could affect them in a variety of ways. And it’s not just obvious which states are the most affected.”
To estimate the effects of the tariffs, the researchers first determined where US imports come from now, how much is paid in tariffs, where the imports go after they cross into the country, and how much those imports make up a state’s economy.
The researchers considered GDP, which measures the value of the final goods and services produced in the state. It also smoothed out the disparity in economy sizes of different states.
“California is going to have a huge amount of imports just because it’s a huge economy. Same with Texas,” McClelland said, noting the analysis included the 60% tariff on China and 10% tariff on all other countries.
While nationally imports accounted for 11% of US GDP in 2023, that differed greatly by state. In South Dakota, imports make up just 2% of its GDP, while the share is 27% for Kentucky. Overall, imports were a bigger percentage of GDP for states in the Midwest and South.
“I didn’t anticipate that Mississippi, Tennessee, Kentucky, Indiana, Michigan would be among the states that ended up with the most imports,” McClelland said. “I was surprised by that.”
Using that information, the researchers could figure out how much Trump’s proposed tariffs would affect the imports going into each state.

Tariff payments would total more than 3% of state GDP in Illinois, Michigan, and Wisconsin; 4% of GDP in Indiana, Mississippi, and Tennessee; and nearly 5% in Kentucky. Without Trump’s policies, tariff payments would have made up less than 1% of the GDPs of each US state.
