>At every step of the way they very eloquently and academically explained why they have the right solutions

Part of the problem is that they didn't explain anything. Even in friendly interviews, the best kamala can answer when asked for specific is a big word salad that can be summarized as "Trump is evil and a danger to democracy, vote for us". Saying you have a plan and shitting on the other party for not having one is not the same as having a real plan and communicating it properly.
