Sarah Palin has already turned out to be a lively Republican candidate for US vice president. To our knowledge no one has yet inquired as to her Jewishness.
Against: There is plenty of stuff here, not least the fact that Palin, then Sarah Heath, was baptised as a Roman Catholic and then rebaptised into the Pentecotal church. Her hobbies are hunting, ice fishing and riding snowmobiles - these are practically enough to rule her out in themselves. She is thought to be a fan of former presidential hopeful Pat Buchanan, famous for his anti Israel diatribes.
For: The Jewishness comes from her husband, Todd Palin. The name is derived from Balin, the Yiddish word for "beautiful". Todd Palin's ancestors migrated from Russia to Alaska, when it was a Russian colony. His mother is called Blanche, a common Lithuanian Jewish first name. Todd may not know he is Jewish but we reckon he is. Sarah is known to have attended a Jews for Jesus lecture (although we don't know if this makes her more or less Jewish) and the boy who impregnated her 17-year-old daughter, Bristol, is called Levi (but we don't think he is one)
Verdict: About as kosher as a ham and cheese sandwich.
