2012 Revenge of the Jews, or of the economy?

Politico reports:

The American Jewish Committee's annual survey of its constituents (and this is American Jewish adults, not voters) is out today, and shows the sort of dramatic drop in support for Barack Obama that you've seen in a range of polls.

Last year, 57% of American Jews approved of his performance; now he's at 45%, bad news in a heavily Democratic group.
