FRESNO — Advocates for the homeless say a clean-cut man who showed up at a Fresno shelter last week looked out of place. Now they know why — it was 41-year-old millionaire Neel Kashkari, a Republican candidate for governor. A former banker, Kashkari rode a bus from Los Angeles to Fresno with $40 in his pocket and a plan to spend a week looking for a job washing dishes or packing boxes.
