The story has it that once, during a battle, one of Napoleon's marshals came up to him and reported that the enemy was making a flanking maneuvre, which was clearly tactically unwise. "What shall we do?" the marshal asked. Napoleon is said to have replied [the provenance on this one is a trifle clouded], "Never interrupt your enemy when he is making a mistake."
I offer this as an explanation for my silence concerning the circular firing squad of Bush, Rubio, Christie, and Kasich that has commenced fire in New Hampshire.
