One chapter in this story took place in July 2005, when the Senate Banking Committee, then controlled by the Republicans, adopted tough regulatory legislation for the GSEs on a party-line vote—all Republicans in favor, all Democrats opposed. The bill would have established a new regulator for Fannie and Freddie and given it authority to ensure that they maintained adequate capital, properly managed their interest rate risk, had adequate liquidity and reserves, and controlled their asset and investment portfolio growth.
Why was there no action in the full Senate? As most Americans know today, it takes 60 votes to cut off debate in the Senate, and the Republicans had only 55. To close debate and proceed to the enactment of the committee-passed bill, the Republicans needed five Democrats to vote with them.
But in a 45 member Democratic caucus that included Barack Obama and the current Senate Banking Chairman Christopher Dodd (D., Conn.), these votes could not be found.
