Harris is appealing to blacks merely because of her race. She has zero personality and has no genuine issues that appeal to the majority of Americans.
I dined last night at a Chinese restaurant, and in the booth next to me were four black ladies, and they talked about politics for much of the evening. They were loud enough, it was hard not to hear their conversation. They all loved Harris, were not very fond of Biden, expressed they liked Buttigeig(which I thought odd), etc. And after talking politics, one of them said, can we just stop talking politics. I suspect she was a Trump fan, for she was silent for most of the time. She sounded irritated with the conversation.
I still say, it will not be any of the leading contenders on the Dems side. What is happening now is merely prologue to the real drama later in the year.
It will be TRUMP vs Clinton again. The Dems have no other play. The repeated sentiment is someone that has a chance to beat Trump. None in the present clown car have a chance, I do not care what any of the polls imply now. The Dems are their own worst enemy, and noise makers like the Anarchist Four complicate their efforts to have a viable platform.
