Israel andThe Democratic Party.
The comment seemed like a casual aside. Ann Lewis, a senior adviser to Hillary Clinton, was touting the New York senator's strong support for Israel during a conference call in January with leaders of major American Jewish organizations. During the call, Lewis energetically contrasted Clinton's pro-Israel credentials with those of Barack Obama. To make her point, she said that Obama's "chief foreign-policy adviser" is Zbigniew Brzezinski, says one participant who would talk about the call only if he were not identified.
It seems the Democratic base has become immune to these attacks (e.g. Joe Lieberman), but the leadership is still concerned about how the party is perceived (rightly or wrongly) on Israel.
