NEW YORK — Bill de Blasio, who ran for mayor of New York promising to address deepening concerns about income inequality and controversial police practices, won far more votes than any other candidate in the Democratic primary Tuesday, according to exit poll results. But it was not immediately clear if he had won the 40 percent needed to avoid a runoff with the second-place finisher, either Bill Thompson or Christine Quinn.
Until a few months ago, de Blasio, 52, had been a distant fourth in the crowded Democratic field, well behind Quinn, the longtime front-runner.
Former Rep. Anthony Weiner, who resigned from Congress in 2011 over sexually explicit online messages to several women, was far behind in the polls.
In the Republican contest, Joe Lhota was battling John Catsimatidis.
A runoff would be held Oct. 1. The general election will be Nov. 5.
In the unexpectedly heated race for city comptroller, Scott Stringer, the Manhattan borough president, was struggling to hold off a surprise comeback attempt by former Gov. Eliot Spitzer, who resigned from office over his patronage of prostitutes.
