1. Kamala Harris is a politician, as is everyone running for national office except for Trump (it is clear what he is, but he is not a politician). She knows how to adjust her views for an audience, and to minimize insulting anyone.
Based on her previous career, she is a full fledged member of the bi-coastal elites, moderate to conservative on criminal justice issues, and in many ways a 100% normal Democrat.
2. Kamala Harris is distinct in that both her parents were immigrants (a West Indian, presumably descended from British slaves as are most West Indians, and an immigrant descended from an upper class caste in India). This election is the first in which none of the candidates for either national offices are descendants of those who were in America at the time of Revolution (all recent immigrants – Trump and Harris from 20th century immigrants, Pence and Biden from mid-19th century immigrants, and not a Anglo-Saxon among them).
