Twelve years ago, Bill de Blasio attended New York City Mayor Michael Bloomberg's inauguration as a newly-minted city councilman, unknown to most outside his Brooklyn district and a small circle of political operatives.

He is now Bloomberg's successor, elected by a record margin, supported by a former — and perhaps a future — U.S. president, and hailed as the face of a progressive movement that pledges a significant realignment of the nation's largest city. (AP)
