Putz is the Yiddish word for penis. D'Amato termed Shumer a putzhead. The only realistic translation is dickhead. The Jewish people there when he said it, and the Jewish people of New York generally, were about as amused as if he gone to a meeting of Blacks and had dropped the N-word.
Ex-Senator D'Amato was the fool. Shumer won the election.
But if you want him as a politician, you can have him. I don't see where he could do much harm to California.
