For almost 35 years, Wyoming entrepreneur Alan Chadwick has run his business importing clothing from China and selling the Western-style gear to stores serving “working cowboys” in the US.

Now, as former President Donald Trump campaigns on a pledge to hit all goods coming into the country with a 10%-20% tariff, or border tax, which would rise to 60% for goods from China, Chadwick is having to drastically rethink his strategy.

The 66-year-old has been exploring moving manufacturing of his products, like wool shirts with snaps and canvas jackets, to India or Pakistan – or perhaps closing his Wyoming Traders business, which employs 16 people, and retiring altogether.

Chadwick said tariffs were a “tax on the American people” and warned that the expense for a company like his of opening a factory in the US was unrealistic.

But as he prepares to cast his ballot, he expects to swallow his qualms about tariffs in favour of other priorities, such as illegal immigration and opposition to abortion.

“I will vote for Trump even though he’s going to hurt our company if he does what he says he’s going to do,” he said.
