Answer:
If you look at it from a logical viewpoint, you may not see the appeal to Kamala Harris, as she has done bad things before (much like any politician.) A major point to people voting for Kamala Harris to be Vice President is the fact that she represents democrats and liberal ideas. She will be the first woman to become vice president, as well. People are looking for a change in government, especially if they were not a fan of President Trump. People voted for her because they voted for President Elect Joe Biden. Some people, despite not liking her, voted for her because they see her and Biden as the lesser of two evils in this election.
