Arizona Gov. Doug Ducey, a Republican, has made several enemies in backing President Trump’s new tariffs on Mexico. Ducey says border states such as Arizona need to prioritize border security over commerce, but his opponents make the opposite argument, as tariffs on Mexico will harm the economies of southern border states the most.

According to the U.S. Chamber of Commerce, an initial 5% tariff would cost Arizona $452.1 million dollars per year. Trump has threatened to gradually raise this tariff as high as 25%, which would cost Arizona $2.26 billion.
