I am relying strictly on memory here. Not too long after the murders, I had read that White resigned so he and his wife could open a seafood restaurant. He explained that he was not making enough money as a member of the Board Of Supervisors. This was shocking to his constituents and other supporters around the city and state. His district was blue collar and filled with people who did not like what had happened to San Francisco's image since the early 1960's with the hippies followed by the gay activists. White was good looking with some charisma and his having been a policeman and fireman also helped him politically. In his brief political career he had convinced a lot of people he would fight with them to "clean up" the city's image from the damage done by the left wing extremists. Many of his supporters saw him as a future candidate for mayor or even statewide office.Mister Tee wrote:One narrative quibble: I was a bit unclear on why White resigned in the first place, so his reversal was hard to put in context (other than the dark intimations of police pressure). This would be one spot where making the film mostly from Milk's point of view, rather than having an omniscient narrator's view, deprived the audience of information it would have liked to have.
He convinced people he wanted to be a Supervisor because he was dedicated to making San Francisco a better place to live and raise a family. For someone like that to give up his office because he was not making enough money was shocking to a lot of people.
For some reason, the restaurant quickly collapsed and White needed his job back. Mayor Moscone decided to appoint someone who was more in agreement with him politically. White's former supporters were not going to bust their backs fighting for him to get his seat back because they felt he had let them down.
