dog whistle politics
n.— «The Americans call this “dog-whistle politics.” Blow a dog whistle, and you won’t hear much to get excited about. But the target of the whistle…the dogs—will detect a sound beyond the audible range of the rest of us, and will react to it. Two quite different messages are contained within the one action of blowing the whistle: the one benign, the other designed to be heard and heeded only by the ears tuned to it.» —“The Dog Whistler” by Tony Wright The Age (Australia) Apr. 8, 2000.
