During the last few days, the whispers have swelled to an angry chorus of frustration about Obama’s perceived weaknesses.

In Connecticut, a businessman who raised money for Obama in 2008 said, “I’m beyond disgusted.” In New Jersey, a teacher reported that even her friends in the Obama administration are grievously disillusioned with his lack of leadership—and many have begun to whisper about a Democratic challenge for the 2012 presidential nomination. “I think people are furtively hoping that Hillary runs,” she said.
