Ari Ben Canaan points out the 19th Century Jewish politician Lewis Charles Levin (November 10, 1808 – March 14, 1860). According to Wikipedia: “Shortly after the 1844 Philadelphia riots, Levin ran for Congress and was elected on his party’s platform: (1) to extend the period of naturalization to twenty-one years; (2) to elect only native born to all offices; (3) to reject foreign interference in all institutions, social, religious, and political.”
Benjamin Disraeli is another example of a Jewish politican in the diaspora campaigning for majority rights. Disraeli was very much a race man. “No one may be indifferent to the racial principle, the racial question. It is the key to world history. History is often confusing because it is written by people who did not understand the racial question and the aspects relevant to it… Race is everything, and every race that does not keep its blood from being mixed will perish… Language and religion do not determine a race—blood determines it.”
