Both Donald Trump and Kamala Harris have campaigned in the Rust Belt city of Erie, Pennsylvania. And control of the White House could come down to how business owners and voters in Erie view each candidate’s economic vision. In every presidential election since 1992, Erie County has gone for the candidate who ended up winning Pennsylvania. Many people in town say they want predictability. They question Trump's ideas on tariffs in particular. But there's also doubt that either candidate can do what's being promised.
