Biden didn’t display a “breadth of knowledge” - he displayed a willingness to recite incorrect statements with a straight face. This is what Washington teaches these people - to lie or make horrible factual errors with an air of certainty. If this is what concerns the editors of this paper, I’m sure Palin will learn to baffle them with BS soon also.
Old Joe used the propaganda technique out of the Army's PSYOPs manual. It's the "Addtional information required to be recognized" technique, page 1 of the Operations Field Manual no. 33-1. "The audience or analyst must have additional information...". In other words, he is a liar.
