I'm easily the most politically engaged person I know. If I wasn't listening (though I was) then that's a really bad sign. We need candidates that drive engagement.
Kamala had a lot going in terms of technocratic improvements that actually would provide some value for voters, but there was nothing transformative, and there was no interesting narrative.
The most interesting thing she did was campaign with Liz Cheney, so that's what got the attention. She wanted to convince right leaning voters that she understood them, but instead communicated that she is just another neoliberal warmonger. It doesn't matter that she might have threaded the needle perfectly in her rhetoric because she stepped into a narrative that said otherwise.
