I share your ambivalence regarding Pat Buchanan. He is a great political thinker but he can definitely go off the deep end from time to time. My favorite Pat Buchanan quote may not have been originally said by him but he is the first one I ever heard say it:"We are going to fight until hell freezes over and when hell freezes over we will fight on the ice." Pat is one pugnacious son of a gun.
My favorite is from the 1992 campaign in South Carolina or somewhere, when he was running for President (and when I supported him, as opposed to recent years). He was making great strides, but of course the Proper Prude media were reminding him that his campaign budget seemed small for what he was attempting. As the primary approached, his numbers were looking inexplicably good. They asked him, "What will you tell your people to do?"
With a chuckle, he answered, "Saddle up, and ride to the sound of the guns."
