Occupy Wall Street protests reveal liberal tensions

The Washington Post reports:

it is unclear whether this sudden burst of energy on the American left will help Obama and other Democrats. The protests are gaining steam around a set of economic grievances and a wariness of both parties’ reliance on corporate campaign money — and Democratic officials are wondering how, or whether, they can tap into a movement that seems fed up with all brands of partisan politics.

That tension has been evident in recent days in debates raging online and in person at demonstration sites across the country.
