Hi,
I came by this excerpt:
The sharp turnabout in tone and substance reflected a recognition not only that Mr. McCain had struck a discordant note at a sensitive moment but also that he had done so with regard to the very issue on which he can least afford to stumble
Could you elaborate on the meaning of "strike a discordant note", please? Does it mean that he had turned the public against him by saying something that made the public turn on him?
Also, is this phrase often used in conversation ?
Thanks !
