You could tell she had those zingers locked and loaded and was just waiting for the right time to drop each of them.
You could also see her when she decided to chamber the round. Where her stern disapproval face had brief flickers of delight as she decided she was going to use one when she had her next chance to speak.
Her prep team was incredible. Overall her campaign is performing incredibly.
I think her campaign is what an actual campaign is supposed to look like, it just looks incredible when you compare it to the dumpster fire that is Trumps campaign.
