My own first association when I hear the name is "just another fundagelical" - if I didn't know better, I'd mark him down as being in Bush/Cheney's camp. And judging by what gets published plagiarised in the Danish press, that's probably the reaction of most Danes...
My guess would be that it doesn't make much difference that Buchannan is not an authority on the matter: Anybody in the target audience who's sufficiently well informed about US politics to recognise the difference between Cheney and Buchannan would probably recognise that argument from authority isn't a valid way of arguing in the first place. So bothering to dig out a bona fide authority is a waste of time.
