Socially definately not (gay marriage and marijuana are steadily becoming more acceptable both to the liberal centre and the general population) and economically they’re merely returning to the tradition of Smith, Cobden, and Peel after the decades of protectionism fostered by World War I and the Great Depression-they don’t support dismantling social welfare programs only in liberalizing trade.
George Soros would be perfectly happy to bankroll them.
As far as I’m aware, Soros hasn’t donated to any individual campaigns, nor has he donated through any official Occupy channels, nor does he even directly fund Adbusters.
