No it isn't. Sour grapes was what Kasick did not honoring his pledge and undermining the convention by not fulfilling duties as host governor. A new day is dawning, and it's a better Republican Party if all of the nevertrump slime just slink away. It'll actually help us win over independents and fed up Sanders supporters.
I’m glad Trump is actually taking care of this. Even though a lot of you will probably gnash your teeth over it, like you gnashed your teeth over his letting Cruz dig a hole till he was out of sight... till you saw the wisdom of it.
So why meet sour grapes with more sour grapes?
