Niki Solis, who was a manager in the city’s public defender office when Harris was District Attorney, says she feels compelled to highlight her achievements, despite the fact that the two were often opposed.
“There is no question in my mind that she was the most progressive prosecutor in California. There’s no question, and for people to even want to debate that is ludicrous to me,” says Ms Solis, now a deputy public defender.
She describes Ms Harris as “receptive, respectful, always professional”, praising her decisions to stop prosecuting underage girls for prostitution – a cause Solis was particularly passionate about – and her steadfast refusal to seek the death penalty, even in a case where a police officer was killed.

Two of her biggest backers have been Susie Tompkins Buell, a co-founder of the clothing companies Esprit and North Face, and Mark Buell, whose career has woven in and out of municipal government and real estate development.
