It's unlikely Kamala Harris will ever be elected president, she's not electable as shown by her primary performance where she dropped out after polls showed her losing to Andrew Yang (holy shit that must've stung) in her home state where she was the sitting senator.

But at the same time I don't think Biden has another four years left, and Trump has plenty of time left to fuck up his own campaign. So in the end, this woman is probably gonna be the president at some point if Biden eeks out a win
