With about 97% of Tuesday's ballots counted, Mr. DiNapoli had 49.84% of the vote vs. 47.04% for Mr. Wilson, who conceded Wednesday morning. Two other candidates shared the rest of the votes.
Mr. DiNapoli, a former state assemblyman, was chosen as comptroller in a joint session of the state Legislature in February 2007, following the December 2006 resignation of Alan Hevesi, who pleaded guilty to state charges of fraud in connection with using state employees to chauffeur his disabled wife.
In October, Mr. Hevesi pleaded guilty in New York State Supreme Court to accepting nearly $1 million in gifts in exchange for approving $250 million in investments for the state pension fund between 2003 and 2006.
Mr. Hevesi's guilty plea was one of several obtained by New York Attorney General Andrew Cuomo as part of lengthy investigation of political influence-peddling in the awarding of investment business for the retirement fund.
Mr. Cuomo was elected governor on Tuesday, soundly defeating Buffalo, N.Y., business executive Carl Paladino. With 97% of votes counted, Mr. Cuomo had 61.52% to Mr. Paladino's 33.99%. Five other candidates filled out the field.
