This is all information that was available before the Nov 2008 election:
And incredibly, Barack Obama was still elected. Despite his enormous contributions to Fannie/Freddie, despite many of his economic advisors being key players in the mortgage crisis and point men who advocated and lobbied the sub-prime industry. Despite that Obama was a lawyer who pushed for groups that wanted easy lending standards that caused the crisis. Despite that Obama, during just three years in the Senate, racked up larger contributions than anyone else in congress.
And the same advocacy of easy lending is still expanding the mortgage bubble under Obama's presidency, setting us up for an even larger collapse!
Also, the subsidies to create "affordable housing" actually made it unaffordable, spiking real estate prices far above what previously only rose roughly equal to interest rates.
Similar to how government subsidies of universities are now making "affordable" college education unaffordable.
