Republican's, due to the need for 60 votes to overcome filibusters by the minority in the Senate, did not have practical "total control" of the congress at any point in the past 8 years. Stop peddling in this misinformation, please.
Republicans had "total control" of the House. They passed, I believe, two bills on this out of committee and off the floor to the Senate. The Senate, though a Republican majority from 2003-2006 and part of 2001-2002, was not a filibuster proof majority at any point and so they didn't have practical "total control" in this chamber. Senate Republicans initiated two bills (I think) of their own on this issue. One never made it out of committee because at the time Democrats were the majority and had control of what passed out of committee on party line votes. They did another in 2006 (the one McCain talks about) and it got out of committee, but was filibustered on the floor, killed by the democrat minority.
Besides these legislative efforts, Greenspan and the former Treasury Sec both testified before congress warning of this problem in the making and asked for needed reforms.
George W. Bush is guilty of pushing for increased national housing goals in the absence of these needed reforms, but the fact is his administration did see the problem, warned of the problem, and pushed for the necessary reforms and the Democrats were energetically opposed in both chambers. GWB tried to have it both ways and deserves some of the blame as a result, but his role in this was split, and regardless he and the last 4 congresses certainly did not create the problem as that groundwork was laid in the 70's and 90's.
Congressional Republicans were not split as a group and were in favor of reforms on this pending problem and Democrats were almost uniformly opposed to such reforms. House Democrat opposition is telling and a clear indictment of the party in their intransigence, lack of concern, and covering for the fraudsters at Fannie and Freddie and in the rest of the industry that handed us this mess, but it didn't matter in a practical sense since the reform efforts made it into bills and were passed out of the House and into the Senate by the Republican majority in that chamber. Senate Democrats, however, either killed bills in committee or they killed them on the floor via filibuster. In both chambers Democrats were steadfastly against these reform efforts. They didn't acknowledge a problem, they voiced support for at least some of the private and quasi-private sector perpetrators, and they used short sighted, despicable rhetoric (largely based in false, latent racism) against those who were trying to stop this problem before it got out of control.
