There is a link, but BO is hardly responsible. He wasn’t even in Congress when the truly damaging legislation was passed. While he supports the Socialist goals of the CRA, he was not a player. The culprits are fairly easy to spot: Chris Dodd (Senate Committee on Banking, Housing and Urban Affairs), Paul Sarbanes (former chair of Senate Banking Committee), Phil Gramm (former chair of Senate Banking Committee and author of Gramm-Leach-Bliley), Barney Frank (CRA and guilty on multiple other counts of demogoguery), Jimmy Carter (the Squish-head who was President when CRA was enacted), Clinton (who presided over CRA being made even worse than it already was), the idiots at non-think tanks such as New America who argued that the CRA had nothing to do with excesses in the housing market despite mountains of evidence to the contrary, and EVERYONE, every two-bit, ward-heeling, cheesy congressman and senator who did everything they could to block the reining in of Freddie and Fannie (see Barney Frank and Chuck Schumer). I could continue, but you get the point. There is plenty of blame to go around.
Move along, and good luck with that job, family, and future retirement thing that you have going on there. Today's politicians will do all that they can to crush your ambitions, in the name of globalism.
Keep the faith!
