Wasserman Schultz has given virtually no indication of which way she’s leaning, but on Thursday she announced that she was bringing Vice President Joe Biden down to Florida to make the administration’s case for the deal to Jewish leaders in the region. “I think that she’s torn,” said Greg Rosenbaum, chairman of the National Jewish Democratic Council, which has come out strongly in favor of the Iran accord.

While Republicans have opposed the agreement en masse, the at-times vitriolic debate has split Jewish Democrats apart in an unprecedented way.  “I’ve never seen an issue this divided within the Jewish community in the United States and between the United States and Israel,” Rosenbaum said. The opposition from Charles Schumer, the Senate’s Democratic leader-in-waiting, caused a rift with the White House, while Representative Jerrold Nadler, a veteran Democrat in the House, has been so vilified by more conservative Jews in New York for supporting the deal that both the NJDC and the Anti-Defamation League have written open letters in his defense.
