To me, the most interesting thing about the Bret Baier - Kamala Harris interview wasn't in the questions asked or answers given. It was in the stage managing. Kamala clearly only has limited number of memorized talking points, and if you are already a Kamala supporter, the answers are fine. Kamala showed up 30 minutes late and informed Fox News the interview had to be cut short, which forced Bret to trim the number of questions thereby cutting the chances Bret would ask her something out of left field she was unprepared to answer.
That weird room they are in with a hard back wall reflected sound which allowed you to hear the people standing behind the camera. When Bret would ask a pointed question and Kamala would start to get angry, you could hear the rustling of her handlers, and finally at the end they put a stop to the interview. The people who know Kamala best, her campaign staff, knows there isn't anything behind the false front and they worked hard to keep that hidden. Part of me believes the Fox crew knew exactly what they were doing when they set the venue up that way.
Now contrast that with Trump in the Bloomberg interview, the NABJ interview, or any of his hostile interviews. There were no handlers seeking to contain Trump, no limits set by Trump on the amount of time, and no limits on questions. Trump walks out and Trump handles it how he sees fit. Some may detest the substance and other revere the substance, but everyone can see there is substance there. That is clearly not the case with Kamala.
