Honestly, I think it is silly to talk so much about Harris herself. Of course she's the one saying most of the stuff and the face of the campaign, but she's ultimately just toeing a line. And all of these politicians know they need to toe the line and not really try to win. I'm sure if Kamala Harris didn't have to satisfy a bunch of capitalists and could do absolutely whatever she wanted she would actually say all kinds of progressive stuff (kinda like she was sort of doing in the Democratic primary). I'm sure she actually really wanted to win, for her own sake. But she would be smeared and instantly kicked out of the race by any person or entity with an ounce of power.
I think most well-known politicians in the US at this point are naked opportunists. And capitalism as a whole is sort of that way. Some people in the security state might be ideological, but I don't feel like any public figures really are.
