And no credible, non-partisan economic group or academic group has disputed these numbers.
CRA had almost nothing to do with the meltdown. That's an empirical fact by now. Freddie Mac and Fannie Mae had their problems, but they were only small fish in the subprime market, and relatively late to the game.
The thing about rightwing partisans and bush apologists, is that they'll hear something on rightwing talk and they'll cling to it for years Regardless of the facts and empirical evidence (e.g., they kept claiming for years that Saddam was an ally of al qaeda, contrary to all credible evidence).. They'll have no credible counter argument against demonstrable facts, as you cite here. Its the deep anti-intellectual strain that runs throughout the extreme rightwing. The only counter argument you'll hear is "The fed sucks!".
Poor people didn't cause this meltdown. And Fannie Mae was only a small time player as the meltdown occurred. It was a failure of the rightwing ideology that claimed free, unregulated markets will police themselves.
