"And the Republicans were in charge of Congress during the time when the Democrats were said in this article to have blocked legislation. How did the minority party block legislation without the support of members of the majority party?"
Easy. By peeling away enough Republicans like Sen. Bennett (with the help of Fannie money) to switch to their side and form a majority coalition to block reforms for Fannie and Freddie. The democrats were solidly against Fannie's oversight then, all they needed were a few repubs to jump ship.
And Daniel Gross:
"The right blames the credit crisis on poor minority homeowners. This is not merely offensive, but entirely wrong."
The Republican aren't blaming blacks and poor people. They're blaming the people who ran fannie mae to the ground (the ground zero for this financial crisis) and it's Democrat enablers. I myself think the idea of expanding home-ownership to poor black communities is a wonderful idea, BUT only if it's done right and without recklessly overdoing it for profit. Everything should be done in moderation.
See, the problem with democrats is that we can't have an honest discussion of how we got into this mess without somebody playing the race card.
THAT'S the problem.
