You are omitting some key facts:
- Willie Brown appointed Kamala Harris to her first two political positions
- Harris was appointed Assistant District Attorney of San Francisco, which helped her run for full District Attorney
- Willie Brown introduced Harris to the entire San Francisco political elite, which served as the base for all her future California campaigns
So yes, Kamala's success is directly linked to the fact that she dated a man with a lot of power who was 31 years her senior.
