INDIANAPOLIS — President Trump’s trade policies are sending tremors across Indiana, as voters reliant on the agriculture and manufacturing industries that are the backbone of a thriving state economy brace for the fallout from retaliatory tariffs being slapped on U.S. exports.

Trump’s aggressive imposing of tariffs on foreign imports to negotiate more favorable trading terms for American products threatens to upend a strong Indiana economy that exports $4.6 billion annually in agriculture commodities, according to government figures. The state is the nation’s fourth largest harvester of soybeans, and more than 100,000 jobs depend on farms that are 97 percent family-owned.
