I did not see Pres. Nixon as being antisemitic. Apathetic yes, but no real hatred (nor real love) for Jews. He was just looking after his own interests, just like all politicians (including Kissenger).
He said, when Golda Meir visited, that he did not want to invite any Jews that voted for the Democrats. That was plain politics. He was saying that he wanted Jews that voted for him to join them. On the other hand, he did not seem to want Irish nor Italians nor Blacks there at all.
