[Political Junkie Too]

You are misquoting the Constitution. The article you site prohibits tariffs being imposed by individual states on goods traded between the several states.

Maybe, maybe not.

I have been using this website as my source for the Constitution. They label Article I Section 9 as "Limits on Congress." They label Article I Section 10 as "Powers Prohibited Of States."

Unless their sub-headings are wrong, they think that Section 9 restricts Congress, not the States.

But the source could be wrong, or over-simplified, I'll give you that. But if they are right, then I'd say that you have it backwards, that it prevents the Feds from taxing goods between the states, not the states themselves. Section 10 clause 2 prohibits the states from taxing imports. or exports.

Here is Section. 8.

The Congress shall have Power To lay and collect Taxes, Duties, Imposts and Excises, to pay the Debts and provide for the common Defence and general Welfare of the United States; but all Duties, Imposts and Excises shall be uniform throughout the United States;

I guess we will have to wait to see which way the Courts rule on it since it not clear cut either way.
