I can't find the statistic but I believe that Lou Lehrman received a bigger share of the Italian-American vote in the 1982 election than Mario Cuomo.
I checked the '84 Almanac of American Politics. Barone stated that Lehrman either carried or "nearly carried" the Italian-American vote in that contest. I think they could tell that their fellow Italian-American Cuomo didn't represent their values, and could best be described by that old Italian phrase, "a schmuck." ;-)
