Ultimately, the best way to root-cause a policy issue is to follow the money. Someone is making money from a lack of governance.
When all viable candidates for a position are already left of center, the only way to shine is to seem more-progressive and out liberal the other guy.

San Francisco has been pushing a hard line anti-car agenda, while making no noticeable improvements to transit. MUNI is a disaster being held hostage by unions. Bending to environmentalists to not address legitimate need for parking. Inefficient responses to groups like Critical Mass that breed resentment against bikes. Refusal to address the vagrant problems resulting in crap covered sidewalks. etc.
