The Cato Institute is making it really easy to discover politicians’ voting records on free trade. With the click of a button, for example, we can find out the trade positions of Dorgan and Wyden, the demagogues who bedeviled Robin Hanson. (You won’t be surprised).

It’s great the Cato is helping to reduce public ignorance. But mightn’t it be facilitating public irrationality? If the public is protectionist (and it is), increasing awareness of trade records could actually hurt free traders.

Should we hope that the Cato label will keep protectionists from finding out who’s really on their side?
