Yes, Rahm Emanuel is a Jew. He was born in Chicago, Illinois in 1959. In Hebrew the name Rahm means "lofty" and the name Emanuel means "God is with us."
Emanuel, the former chief of staff to President Barack Obama, won the Chicago mayoral election over five other challengers Tuesday 2/22/2011, topping the 50% threshold to avoid a runoff vote. He is the first Jewish mayor elected in Chicago.
The Times Sunday Magazine had a profile of him (3/14/2010), "The Limits of Rahmism," By PETER BAKER, "He was chosen as White House chief of staff because he could make things happen. What happened?"
Rahm's father Benjamin M. Emanuel was born in Jerusalem. He was a member of the Zionist group the Irgun during the British Mandate of Palestine. He is a pediatrician.
His mother, Martha Smulevitz, worked as an X-ray technician. She was the daughter of a local union organizer and herself was a civil rights activist.
Rahm attended Bernard Zell Anshe Emet Jewish Day School when his family lived in Chicago. He and his family are members of Anshe Sholom B'nai Israel, a modern Orthodox Jewish congregation in Chicago.
