Zaybay, where is that data from? If Reagan really did worse with Jewish voters in 1984 than 1980, it does indicate that foreign policy re: Israel is a huge vote-mover. But I'm skeptical.
Yeah, Comerade Funk made it by going back into the election files. Its a pretty great graph.
Anyway, while you could make such a connection, there really isnt any correlation elsewhere. Its much more of a coincidence than anything else(it seems a lot of Jewish voters in 1980 went to Anderson who would normally vote Democratic, so just like with Debs and Wallace, Im not sure if using such numbers when a 3rd party did rather well is analytically wise).
