To me, you can interpret two ways: "She doesn't know anything about the You Crane" or "She thinks her audience is so stupid that she has to dumb it down to kindergarten level". Neither is a good thing. If Biden dropped out as President, I think she would actually be a worse President which is not an easy thing to do.
At least with Biden there's someone behind him pulling his strings who is
competent in their own way, although I'm 180 degrees away from them on almost every issue.
With Kamala, I'm not sure she'd listen to anyone else, so what you see is what we'd get. I see her as lazy, vacillating, and indecisive, which is much worse for a POTUS than a competent (or
semi-competent) person pulling the strings on the person Elon Musk described as a wet sock puppet.
