Harris isn’t a bad person or unlikable. I just think she isn’t good at public speaking. IMO.
This. To answer to question, no, and they aren't going to. Even if she is a bit of an embarrassment, by no means is she scandal-plagued or toxic enough to warrant being thrown off. Pushing her off would enrage black women or wtv group supports Harris (unless Biden replaces Harris with another black woman - I'm not sure who he might pick) and it would be like admitting and acknowledging an issue that does not actually exist (it's mainly just a GOP narrative used to sow seeds of discontent). It would definitely give Harris more importance and attention than she currently has, which is bad - the campaign needs to be only about a.) Biden's positive achievements and b.) what a terrible threat to democracy Trump is.
