Nell Soto, Norma Torres and Pomona
In connection to this story about about Soto's replacement, a local city official noted that Soto more than "sort of mentored" Torres. In fact, this official said that Soto has long had power in Pomona even after she left the city council and has helped Torres for a long time. One interesting tidbit was that Soto, before her current health problems, was going to endorse Torres and then run for Pomona mayor, this official said. Looking over the list of challengers, I can't see anyone else who has a chance.
