“One of the first things I do in terms of executive order if I win,” Donald Trump said Thursday in New Hampshire, “will be to sign a strong, strong statement that will go out to the country, out to the world, that anybody killing a policeman, policewoman, police officer, anybody killing the police officer — death penalty. It’s gonna happen, okay?”

How can it be, one wonders, that the national polling frontrunner for the Republication nomination, the leader in New Hampshire at the moment, knows so little about the job he seeks?
