...the Bush administration warned in the budget it issued in April 2001 that Fannie and Freddie were too large and overleveraged. Their failure "could cause strong repercussions in financial markets, affecting federally insured entities and economic activity" well beyond housing.

Mr. Bush wanted to limit systemic risk by raising the GSEs' capital requirements, compelling preapproval of new activities, and limiting the size of their portfolios. Why should government regulate banks, credit unions and savings and loans, but not GSEs? Mr. Bush wanted the GSEs to be treated just like their private-sector competitors.

But the GSEs fought back. They didn't want to see the Bush reforms enacted, because that would level the playing field for their competitors. Congress finally did pass the Bush reforms, but in 2008, after Fannie and Freddie collapsed.

The largely unreported story is that to fend off regulation, the GSEs engaged in a lobbying frenzy. They hired high-profile Democrats and Republicans and spent $170 million on lobbying over the past decade. They also constructed an elaborate network of state and local lobbyists to pressure members of Congress.

When Republican Richard Shelby of Alabama, then chairman of the Senate Banking Committee, pushed for comprehensive GSE reform in 2005, Democrat Sen. Chris Dodd of Connecticut successfully threatened a filibuster. Later, after Fannie and Freddie collapsed, Mr. Dodd asked, "Why weren't we doing more?" He then voted for the Bush reforms that he once called "ill-advised."

But Mr. Dodd wasn't the only Democrat to heap abuse on the Bush reforms. Rep. Barney Frank of Massachusetts defended Fannie and Freddie as "fundamentally sound" and labeled the president's proposals as "inane." He later voted for the reforms. Sen. Charles Schumer of New York dismissed Mr. Bush's "safety and soundness concerns" as "a straw man." "If it ain't broke, don't fix it," was the helpful advice of both Sen. Thomas Carper of Delaware and Rep. Maxine Waters of California. Rep. Kendrick Meeks of Florida berated a Bush official at a hearing, saying, "I am just pissed off" at the administration for raising the issue...
