Kamala lost because she was too close to the administration that is blamed (rightly or wrongly, doesn’t really matter) for the cost of living crisis.

It also didn’t help that she was thoroughly uninspiring. The best part of her campaign was the actually refreshingly left wing (by american standards) walz.

It marked the third time that the Democrat party has run a soulless career establishment politician against trump. They only won the time before because Trumps fuck ups were immediately apparent and fresh in everyones memories.
