One you missed was Rogan. And not the decision not to go on, but whoever thought it would be good to lie about the reasons. The campaign could have simply stated that scheduling didn't work. Texas wasn't a swing state hence Kamala didn't need to spend money visiting it. Instead they wanted it entirely on their terms and when they couldn't get that, they blamed Rogan. So they not only didn't court the base that Rogan's show has, they alienated it.
Kind of related, Arsenio Hall was just on Rogan and I listened to them talk about Clinton being on and how they offered an interview with Bush as well, but Bush declined as it was 'unbecoming of the presidency'. You could argue Clinton won in large part to what his appearance on that show meant to his campaign. In seeing Hillary in interviews now, I think she could have came across very well on Howard Stern, who knows what that could have done. Just not sure if Kamala has the charisma to make it happen, but wish she would have tried.
