I must say, I think this whole engagement helps Hillary. Whatever else you can say about Hillary Clinton, she knows her stuff. She's a pro. It's very hard to imagine any of the Republicans presidential candidates being able to roll with this kind of questioning, or have even remotely this range of knowledge. For her interlocutors here, who mainly come off as jokes, and for the whole GOP caucus, you can see why they just couldn't and can't forgive Kevin McCarthy for his goof. He really screwed the pooch.
