Nope! No cigar! Generally speaking that history is on the Dems side. Once the Congress became Dem ran, Pelosi did pass a reform bill in '07.
"On 31 July 2007, after the Democrats obtained control of the Congress in the November 2006 election, House Speaker Nancy Pelosi introduced HR 3221, a "bill to provide needed housing reform and for other purposes." Among other things, the bill granted the newly formed Federal Housing Finance Agency "supervisory and regulatory authority over Fannie Mae, Freddie Mac, and the federal home loan banks (enterprises)" (per CRS analysis).
Pelosi's bill became Public Law 110-140 on 19 December 2007"
But it didn't happen the previous years with a Pub Congress. They (the Democrats) are the party that has championed regulations. Only once in while does a politician within the Pub party break with traditional Republican views. BTW Ron Paul was years ahead of McCain for speaking out in concerns of today's market.
