It's clear that the public is anxious about the state of the economy and the inability of Congress to address important problems, given intense Rethuglican partisan obstruction of every Obama proposal. What the 99% / Occupy movement has done is provide a voice to a shrinking middle class that's been hurt by corporate and financial predators enriching themselves over the years.
In a new poll by the New York Times and CBS, the public is increasingly aware of the lines being drawn, and a growing number of the public supports the 99 percenters. Moreover, seventy percent see the Rethuglicans as serving the wealthy at the expense of the middle class. We can't tell whether this movement will grow further and be a force that defeats Rethugs at the polls in 2012, but at a minimum it's shifted the narrative to jobs, income inequality, and economic justice at long last.
