I remember going to a Pat Buchanan fundraiser when he was running for President. I still have a signed copy of 'A Republic not an Empire'.
Reading his books and essays now makes him look like Nostradamus.

A more recent example is Michelle Malkin:

They banned and cancelled her and then she just gave up and ran for cover.
