McCain has enlisted high-profile help of his own to help win Jewish votes: Connecticut Sen. Joseph Lieberman, a self-described "independent Democrat" who has criticized Obama's leadership qualities, has agreed to head up a booster group called Citizens for McCain. In a brief but animated Senate floor confrontation last week, according to a campaign aide who asked for anonymity when talking about private discussions, Obama told Lieberman he was surprised by Lieberman's personal attacks and his half-hearted denials of the false rumors that Obama is a Muslim. (The aide says Lieberman was "strangely muted" during the exchange; a Lieberman spokesman says the chat was "private and friendly.")
