My view at the start of the night was that Booker needed to differentiate himself in a positive way from Harris and I think he did that -- not with any particularly interesting strategy or by taking her on directly, but just from being fairly sharp throughout the evening when she was quite uneven. Will it move the polls? I don't know. I think Harris might be in for a skeptical news cycle or two given that she already has lost a lot of her bounce from the first debate.
