There is a lot in this piece by Johnathan Alter, but i found it pretty well rounded and it brings forth some pretty good points...

Like the Tea Party on the Republican side, Occupy Wall Street makes the party establishment nervous. It's not just that Democratic candidates have done well fundraising on Wall Street in recent years. The bigger problem is getting the activists to draw a distinction between bringing specific greedheads to justice and mocking those parts of Wall Street that are blameless in the 2008 crash and do plenty to invest in the future of the country.

The arguments I heard from the often-articulate protesters in the park were economic, not partisan. None of the posters depicted Romney, House Speaker John Boehner, or any other Republicans. Instead they said things like "Top 1% Want Everything," "Listen to the Drumming of the 99% Revolution," "Stop Off-Shore Tax Evasion," and "Protect Medicare, Not Billionaires."
It's easy to denigrate the movement for simplistic sentiments that lack a clear agenda. But as the Tea Party demonstrations showed in 2009, that very shapelessness is a huge asset (to use the Wall Street term). If "We're the 99 percenters" catches on, and the crazies can be marginalized, then the challenge will be to move from the streets to the ballot box, as the Tea Party did in 2010.

To make something lasting of this movement, the left must move from legitimate moral outrage to a disciplined approach for electing candidates who want to make Wall Street more answerable for the mess we're in. Even as they're outspent by the Koch brothers and their corporate ilk, the 99 percenters will make 2012 a helluva lot more compelling.
