I think Harris team is wary of gotcha moments that could do more harm than good. Kamala went on the Call her Daddy pod the other week, but as far as I know, the chat was fairly basic and didn't dig too deep, much different to what can be expected from Joe.
Yep, rumor had it that they needed all of the questions beforehand, which is simply impossible on a long-form podcast. I really don't get it though - if she's such a brilliant prosecutor then surely a simple conversation answering questions from a fairly neutral podcaster should be no issue. How the hell is she supposed to run the USA if she can't even do that without training wheels?
