As political observers we often focus on text at the expense of subtext, the libretto at the expense of the score, where the real story is told. The big winner tonight was Kamala Harris. She was consistently strong in her answers. Her dramatic confrontation with Joe Biden is clearly the story of the evening. But again, score over libretto. Somewhat like Booker last night but much more so, she took possession of the room and turned it to her advantage. She repeatedly kept talking until she was done talking and did it without sounding rude or grating. She could do that because she embodied command. She made the moderators sound annoying. She continually showed through actions rather than words that she’s powerful, that she shapes the moment rather than being shaped by it. This sort of demonstration of command is always important. It’s especially important when the ultimate opponent is Donald Trump. She was far and away the big winner.
