They needed chess clocks to control each other’s microphones.
For twenty years I’ve been saying that having a human moderator is evil - it positions some reporter above the future (and often the present - POTUS). They should control the microphones with a chess clock, and just go at it.There would also be something to be said for having a slow-motion “postal chess” version in which each comment is, instead of being off-the cuff, a thoughtful one in text.
But we all understand that journalists/Democrats would never agree to that.
