Barack Obama should heed MoveOn.org’s call to try to block the overhaul of the Foreign Intelligence Surveillance Act, as that would harm Democratic unity at a time when Obama needs it, writes Moe Lane. The biggest danger to Obama’s campaign is Obama himself, as he has undermined his own call for new politics by taking a “garden-variety liberal” postition in support of habeas corpus rights for terror detainees and by moving to the center on his pledge to meet with rogue nations’ leaders, according to Mark I.
