He didn't blame Obama for it, although the housing policies Obama and your corrupt party put in place and protected from Bush's attempts to reform them were the primary cause.
Obama was also the #1 recipient of Fannie Mae campaign funds.
And Obama's leftist policies made the recession far worse and far longer than if he'd followed effective policies based on 200 years of accepted Economics. A strong recovery would have begun immediately
and likely most of the job losses never would have happened.
If you understand anything about Economics, that would make sense to you.
