Crockett did hide it in a more sophisticated hypothetical, but even without that it was an acceptable level of raising the stakes, and Greene did open the door to the whole thing by being indecorous in the first place. I don’t know if they’re smart enough or deep enough to strategize aforethought, like, “I’ll just mention a minor thing, they’ll go over the line in their response, and then they’ll get blamed for the whole thing”, but that did appear to be the goal here, and it did work for their side.
I’m as close to 100% certain as I can be that had Greene not called out the physical appearance of Crockett, Crockett would not have called out Greene’s appearance at all. In this new age of playground insults in politics, I don’t blame Crockett at all for not just grinning and bearing it. I say, good for her.
