On one hand, Kamala only had a few months of campaigning while Trump essentially did for years.
But she was part of Biden's administration as the VP, and I think it's difficult for a woman to win in USA unfortunately. They'd rather elect a convicted felon.
Sounding like an idiot when you speak does not appear to be a disadvantage. But eloquent speakers like Obama have won as well.
I think a lot of this comes down to "egg price high" and people not realizing that Biden inherited and operated under Trump's economy, while Trump inherited Obama's.
Democrats fix the damage they do, but get the blame for it.
