It's more about neighborhood level obstruction in SF. People will elect pro-housing candidates as Mayor and State Senator/Rep, but the local Board of Supervisors (the city council) is controlled by people that will say, "you should build that anywhere, but here." People are _very_ anti-change and especially don't want people different from themselves moving in.
