Gov. Gavin Newsom has taken grief for failing to fulfill what seems like a pretty achievable campaign promise: appointing a homelessness “czar” to help the 150,000 Californians living in shelters and on the streets. Newsom’s quest, which at various points had the mayor of Sacramento, the state secretary of health and human services and a Washington DC-based consultant co-wearing the “czar” crown, culminated earlier this month in a Truman-esque “buck stops here” declaration.
