NEW YORK CITY - Millions of New Yorkers go to the polls Tuesday to elect a new mayor, with left-wing progressive Bill de Blasio tipped for a landslide victory to replace billionaire Michael Bloomberg.
The 52-year-old public advocate and his black formerly lesbian wife promise a new style to a city transformed by 12 years of tough love under Bloomberg, who is not standing again.
De Blasio's campaign has left Republican rival Joe Lhota trailing in the dust, picking up on the worries of the economically vulnerable middle class and tapping into a once reliably Democratic electorate.
An NBC-Wall Street Journal poll on Monday gave him an historic 41-point lead over Lhota, putting him on course to be the first Democrat elected mayor of the biggest US city since 1989.
But, with turnout typically weak for mayoral elections, de Blasio used the final day of campaigning to urge supporters to make good on their promises and to go out to vote.
"You have to go into every neighborhood and tell people how much this matters," he said, pressing the flesh in his home borough Brooklyn in the early morning winter chill.
By trading heavily on public appearances with his wife Chirlane and teenage children Dante and Chiara, he has connected to ordinary families trying to make ends meet and a vastly diverse electorate.
His multiracial family has struck a chord in a city of great ethnic diversity: 33.3 per cent of New York is white, 25.5 per cent black, 28.6 per cent Hispanic and 12.7 per cent Asian.
