It is called "Right from the Beginning" or something like that.
As I recall, it is relatively noncontroversial, and was written before he was commonly perceived (by his detractors) to be a racist.
Buchanan went to the Columbia School of Journalism and had to be pugnacious to assert his points of view.
He stayed that way when he teamed up with RM Nixon to help him make his comeback from 1966 onward.
Having read this book, I do not have the impression that he is a racist.
I do believe that he will make his arguments (many nonconventional) and is not deterred by name-callers.
Obviously, one of the most potent names you can call someone nowadays is 'racist'.
Because Buchanan has his own points of view regarding foreign policy, immigration, etc., he gets called a racist all the time.
Just because someone is pro-American culture and wants to see American interests attended to, first and foremost, by American politicians, does not make him a racist or anti-Semite, in my opinion.
And, I honestly do not think I have ever seen him express racist or anti-Semitic opinions. If he did, he would not be on the mainstream programs as much as he is. And, it would be inconsistent with his Roman Catholicism, in my opinion.
But he definitely is not PC, and does not parrot the PC line, and does not cave when he is called a racist.
Obviously on matters related to immigration he will get the racist catcalls a lot.
Because anyone against open-borders-immigration has GOT to be racist, right?
