Kamala, Nancy Pelosi, AOC.etc are politicians with very high unfavorable ratings. And those ratings have a lot to do with their policies and allegations of corruption rather than being a female. If you want to look at female politicians with high approval ratings, look at senators such as Tammy Baldwin, Maria Cantwell and Maggie Hassan.
BTW, I don't think that we need to debate on the suitability of Kamala anymore. Biden is very close to announce his intention to run for POTUS 2024. Check this article from NY Post:
https://nypost.com/2023/01/07/joe-biden-all-in-and-readying-launch-of-2024-campaign/Given his approval ratings (40% to 45%), I would have expected him to step down and pass on the baton to someone like Pete Buttigieg or Gavin Newsom. But given the pathetic state of the GOP right now and infighting there, even if the Dems nominate someone like Kim Kardashian or Justin Bieber, they will win easily.
All those three are white women, and kamala is not, neither AOC, which is why people dislike them and nothing more. You want proof? One of the people you named is leading the LGBTQ+ community in congress right now, as far left as it gets idea and not even supported fully in democrat party, and she was seen as "acceptable" to you. Kamala is not leftist, not at all, AOC is, there is a difference between them, and Bernie is even more left than AOC, and yet like I said neither Kamala nor AOC was seen acceptable whereas Bernie was, there is absolutely no idea aside from them being women of color that prevents their nomination being acceptable.
But I digress, Biden will be nominated again, and he definitely lacks the brain capacity to run a nation and yet for some reason or other, USA will pick him again, interestingly the correct choice to make, a brain dead Biden is still better than Trump for them, I would agree.
