Trying to connect McCain, Gramm-Leach-Bliley to the housing bubble is pathetic. Bank diversity has nothing to do with it. Funny how the article doesn’t mention the over whelming vote for it, along with Clinton signing it.

The Bear Stearns collapse was a result of subprime loans or Community Reinvestment Act (CRA) loans that the democrats pushed on banks.

The CRA was passed into law by the U.S. Congress in 1977 as a result of national grassroots pressure for affordable housing, and despite considerable opposition from the mainstream banking community. Only one banker, Ron Grzywinski from ShoreBank in Chicago, testified in favor of the act. [1]
The CRA mandates that each banking institution be evaluated to determine if it has met the credit needs of its entire community. That record is taken into account when the federal government considers an institution's application for deposit facilities, including mergers and acquisitions.

Wiki can explain this to you and here’s a little snip;

In 1995, as a result of interest from President Bill Clinton's administration, the implementing regulations for the CRA were strengthened by focusing the financial regulators' attention on institutions' performance in helping to meet community credit needs. These revisions[1] with an effective starting date of January 31, 1995 were credited with substantially increasing the number and aggregate amount of loans to small businesses and to low- and moderate-income borrowers for home loans. These changes were very controversial and as a result, the regulators agreed to revisit the rule after it had been fully implemented for seven years. Thus in 2002, the regulators opened up the regulation for review and potential revision.

But guess what, when Bush tried to reform policies the democrats blocked it.

In 2003, the Bush Administration recommended what the NY Times called "the most significant regulatory overhaul in the housing finance industry since the savings and loan crisis a decade ago." [5] This change was to move governmental supervision of two of the primary agents guaranteeing subprime loans, Fannie Mae and Freddie Mac under a new agency created within the Department of the Treasury. However, it did not alter the implicit guarantee that Washington will bail the companies out if they run into financial difficulty; that perception enabled them to issue debt at significantly lower rates than their competitors. The changes were generally opposed along Party lines and eventually failed to happen. Representative Barney Frank (D-MA) claimed of the thrifts "These two entities -- Fannie Mae and Freddie Mac -- are not facing any kind of financial crisis, the more people exaggerate these problems, the more pressure there is on these companies, the less we will see in terms of affordable housing." Representative Mel Watt (D-NC) added "I don't see much other than a shell game going on here, moving something from one agency to another and in the process weakening the bargaining power of poorer families and their ability to get affordable housing."

Now you can read the rest at Wiki for a real education and don’t forget to check out where McCain wanted to reform policies in 2005 but got nowhere.

Yes the democrats are really looking out for the people. On how to screw them with there own money!
