NEW YORK — Democratic Gov. Mario Cuomo, considered a possible presidential contender for 1988, easily won a second term, crushing his under-financed Republican opponent, Westchester County Executive Andrew O’Rourke.

First-term Republican Sen. Alfonse D’Amato appeared headed toward a landslide victory against Democrat Mark Green, a former Nader’s Raider.

With 7% of the vote counted, Cuomo had 180,531 votes, or 67%, to 81,461, or 30%, for O’Rourke.

D’Amato had 152,465 votes, or 58%, to 106,733 votes, or 41%, for Green with 7% of the vote in.

Polls indicated that Cuomo stood a good chance of breaking the 104-year-old record victory margin in a New York gubernatorial race.

before the election record keepers were looking at the victory margin tallied by Grover Cleveland, elected governor with 58.4% of the vote in 1882. Two years later, he was elected President.

Cuomo, 54 raised more than $9 million and spent $5.8 million on the campaign at last filing. O’Rourke had spent only $1.04 million, mostly on commercials in which he debated a cardboard figure of the governor.

In a campaign devoid of issues, the 53-year old O’Rourke tried to make one of Cuomo’s refusal to debate him. But a debate held in the last weeks of the campaign caused no fireworks.
