She was weak on messaging, but her proposal for housing was good (improving affordability has appeal, but she failed to capitalize on it). What confounded this in part was that she probably meant to mostly stay in line with Biden's policies, and you can't connect with voters on that. They're concerned about inflation and the border. Biden's administration already fucked that up for her; they fixed the border, but too little too late (so what is there to say?), and while inflation has abated and wage-growth has improved, people still feel poorer than before 2020 (so what is there to say?).

I can't see how anyone else in her position would have done much better. I don't blame Harris much.
