The debate on the credit crisis can be winnowed down to this basic line: John McCain blames a few bad apples — in this case Fannie Mae and Freddie Mac (and, by extension, the people who relied on these institutions to ensure that banks would provide them loans — i.e., the poor and those living in poor and minority neighborhoods); Barack Obama blames deregulation.
McCain’s argument ties to his “clean up Washington” rhetoric, to eliminate corruption without upsetting the basic free-market structure; Obama’s focus on reigning in the excesses of the free-market.
