Politicians in San Francisco don’t face partisan challengers so the rarely are held to account for their ideas. Just like you’d never get fired buying IBM, in San Francisco, you won’t get fired by going as far left as possible. The two party system provides a healthy sanity check on going too extreme — there is no such sanity check in places like San Francisco. For example, what would happen if a Republican mayor were elected? In New York it worked out pretty well and resulted in low crime and a strong economy; not all Republicans are great and not all Democrats are great, but one thing I could hope we could agree on is that all Democrat (Republican,) all the time has created a paucity of new ideas or new approaches: it’s just more of the same: throw more money at the status quo, grandstand about how compassionate you are and let the limousine-liberal guilt enable existing politicians just continue to waste money and solve nothing.
