Well, the guys a troll, but there is SOME truth in it.
Probably the most unsustainable part of the housing bubble was subsidized mortgages for minorities, black in particular. That was mostly under the CRA (Community Reinvestment Act), which was first put into place by Jimmy Carter, and then put on steroids by Bill Clinton.
The Congressional Black Caucus played an important part, along with Barney Frank and Chris Dodd. They rotated in and out of congress and Fannie Mae and Freddie Mac.
Curiously, the only known time that Obama ever practiced law was in Chicago, where he sued various banks and forced them to give out substandard loans in black neighborhoods.
Bush actually tried to back away from this. But the Democrats in congress resisted, and as was too often the case, Bush gave in and went along with them. The Democrats were the chief guilty party, but Bush did little or nothing to restrain spending in this and other areas. Of course, Bush was not the only one; numerous RINOs were only too happy to play the game of corrupt spending with the Democrat enablers.
So, Obama actually had a hand in creating this mess. But Bush bears some guilt for not doing enough to put an end to it. He had his strong points, but controlling spending and facing down corrupt Democrats and RINOs was not one of them.
“But Bush bears some guilt for not doing enough to put an end to it.”
Where Bush failed was in not standing up to the Media Spin on this issue, controlled by the Democrats.
He had the same issues with the wars, too. The “R’s” were, and still are, terrified of looking bad, or mean, in the media.
He failed to use the “Bully Pulpit”, and didn’t think it was useful to waste time countering the lies of the Left, until it was too late.
