This was a long-term plan. Wipe out the banks and Wall Street through Fannie and Freddie. This was helped by Soros and his hedge fund (shorts) pals, the Chicago Options Exchange (Obama & Rham Emmanuel are plugged there).
They are getting rich wiping out the global financial system to then get Obama elected.
It was also helped by the MSM and Soros knew he could count on them too.
