Yes, that was precisely my point -- that people tend to underestimate Italian-American solidarity on this, at least in the privacy of the voting booth. The difference with the Jewish situation is that discrimination against Italian-American's is still a permissible form of bigotry. And many Italian-Americans are tired of it and resent it.
And in any case, I didn't even begin to get into the factor of the solidarity of opera lovers, who simply cannot believe the prospect of having an American President who not only has attended the opera, but has hosted Live From the Met . . . another small (but not neglibile, it numbers in the millions) group of predominantly Democratic zealots who, again in the privacy of the voting booth, will be pulling the lever with Giuliani.
