Peter Beinart, earlier today in The Daily Beast.  Concluding three paragraphs of this short piece:

...But in retrospect, the netroots movement’s focus on candidates as a vehicle for change left it unprepared for the aftermath of Obama’s election, when Obama failed to articulate a story about why the financial meltdown had occurred—and why America’s regulatory system and welfare state needed to be rebuilt—that could compete with the Tea Party’s narrative of a government grown so large that it was stifling both economic growth and personal liberty.

Today’s Wall Street protests represent the left’s decoupling from Obama and the Democratic Party, something that the global nature of the movement will only reinforce. That doesn’t mean the movement has a clear critique of unregulated capitalism yet, let alone a concrete agenda for reform, but it means that the left finally is forcing those questions onto the public agenda. By confronting Wall Street, it is creating the populist energy that Obama himself has not.

What we are witnessing in Zuccotti Park actually represents an improvement over the Obama campaign. That campaign was largely about faith in one man. The Occupy Wall Street movement, by contrast, represents a direct reckoning with the most powerful forces in American life, forces that are not voted in and out of office every two or four years. And it represents a belief that young Americans must force that reckoning by themselves. No politician will do it for them. Those instincts are exactly right, and we’ve never needed them more.
