Our friends at the Washington Examiner ask if Lincoln would have droned Robert E. Lee. If they read their Eric Wittenberg, they would know that yes, of course, because Lincoln droned Davis. He droned the bejeezus out of Davis!
Lincoln was not a boundaries sort of guy. He was not afraid of the odd precedent. His trailblazing made him a victim of some sic semper tyrranis. In other words, he got droned himself and Davis successfully disavowed any knowledge.
Perhaps you've heard the phrase "disavowed any knowledge?" It seems to have entered popular jargon in 1966.
