Alrighty then
Most of those "Fuck Yous" you mentioned came from Republicans.
Let's look at this going back a wee bit.
1. The Clinton administration asked Fannie Mae to expand mortgage loans to low and monderate income borrowers in 1999.

2. In 2000 antipredatory lending rules were enacted to prevent subprime loans from being credited toward affordable housing goals.

3. In 2003, the Bush administration suggested sweeping reforms in the housing finance industry. These reforms were opposed by some Democrats most notably Barney Frank the highest ranking Democrat on the Financial Services Committee. Note this was all just talk at this time because there was no legislation being introduced.

4. In 2004, the antipredatory lending rules enacted in 2000, were dropped.

5. It wasn't until 2005 that the Republican controlled congress introduced any legistlation. The bill didn't make it out of committee to the Senate.

The links do give some support to your claims. McCain was a co-sponsor of the bill. Thing is, you ignore that the Republicans controlled the Senate in 2005. You ignore the House overwhelmingly passed their own regulatory bill (331 to 90) which lots of Democrats voted for. You also ignore the Democrats that also introduced reform bills of their own in the Senate. All told six reform bills on the subject were introduced in 2005. Just six. I do commend McCain and the others for recognizing a problem and wanting to fix it. My respect for him has increased a notch. I was unaware of this. Thanks for bringing it to my attention.
However, in 2005 times were good and all the regulatory stuff was just not a priority. There were a few on both sides in the Senate that wanted changes but the rest of them didn't seem all that interested. The Bush administration talked the talk but didn't walk the walk and the Senate dropped the ball. (Jeez how's that for overuse of cliches, heh) Your claims of Democratic obstructionism don't have much weight. Neither side did anything. The warnings for the most part fell on deaf ears.
Also, this crisis is not just a result of a failure to properly regulate Fannie and Freddy. The primary lenders were involved in their own risky schemes. Schemes they wouldn't have been allowed to engage in were it not for the dismantling of regulations under the Reagan administration with the Garn-St. Germain Depository Institutions Act in 1982.

Whew. Sorry to bury you in links but the facts of the matter are just not that simple.
