Very true (and very wise on their part).
What "populists" ignore is that Hamilton (and Washington) also believed in federal supremacy, implied powers, and created the First Bank of the United States (a central bank which most "populists" regard as part of a "Judaeo-Masonic-Communist conspiracy"). Some "right wing populists" even advocate total nationalization of the entire financial sector.
You're right, though, that traditional Federalist/Whig/Republican policy is the protective tariff. Why so many Republicans today forget that is as troubling as populists' forgetting that the Federalists were pro-bank.

How nice of you to pigeonhole populists as conspiracy cranks. Did you poll them, or is this data of the Wild Assed Guess sort?
