And most of them are red states, according to a document released this morning by the Koch Industries-backed advocacy groups Freedom Partners and Americans for Prosperity.
The report claims that all 50 states will suffer damage to their economies, but separates out the top 10 most vulnerable to higher import tariffs. Seven are states held by Donald Trump in November, including, in descending order of vulnerability: Michigan, Louisiana, Tennessee, Kentucky, South Carolina, Texas and Georgia.
The three states in the top-ten won by Hillary Clinton include New Jersey, Illinois and California.
Koch Industries is controlled by CEO Charles Koch and his brother David, who have long been outspoken critics of the 20% border adjustment tax championed by House Republicans including Speaker Paul Ryan.

CEOs from across the retailing sector, including the heads of Walmart and Target, are concerned a tax on the imports they sell to U.S. consumers will push up product prices, sapping demand, eroding their profits and damaging the wider economy.
CEOs of big exporters, including Boeing and GE, however, support the plan, which would free export revenue from taxation and help fund a cut in America’s headline corporate tax rate.

“While the Senate has signaled this proposal won’t pass muster, the continued push for a 20% import tax in the House is endangering our chance to achieve comprehensive tax reform.”
Some Senate Republicans have indeed suggested they’re uncomfortable with the tax, making its evolution into law fraught with hurdles, given the Senate is only held by a slim majority.
And the last thing Trump needs is for his tax plans to fall into disarray after the failure of his heathcare plan.
