From an excerpt of Ari Berman's new book, Herding Donkeys: The Fight to Rebuild the Democratic Party and Reshape American Politics:
The White House doesn't want its activists to disrupt the backroom deals its aides cut with lobbyists and legislators, nor does it want them putting too much pressure on obstructionist Democrats, lest it alienate key swing votes in Congress. When MoveOn.org ran ads targeting conservative Democrats who were blocking healthcare reform, Rahm Emanuel memorably called the ads "fucking retarded." And, indeed, the White House has expended considerable political capital denouncing the "professional left" and defending apostate Democrats like Blanche Lincoln in Arkansas from insurgent primary challengers, which has further undermined Obama's reformist brand.
"I'm not looking to pick another fight with Rahm Emanuel, but the contempt with which he held the progressive wing of the party was devastating and incredibly demoralizing," [former Democratic Party chief Howard] Dean says. "That's basically saying to your own people, You got us here, now F-you."
Emanuel received a standing ovation in the East Room from the White House staff on Friday morning when President Barack Obama officially announced his departure.
