At the end of this a mighty jeremiad for the protectionists’ cause, effluent with classical allusions and appeals pro patria, Pat Buchanan writes the following:

If they [advocates for free trade] are right, we are Cassandras. If they are wrong, they are fools who sold out the greatest country in all history for a mess of potage.

No, that is incorrect. If free-traders are right, then you are most definitely not Cassandras. The curse of Cassandra was to be forever right but forever ignored. To be shrill and incorrect ? that’s more the domain of Chicken Little.
