It is amazing what an all out mud slinging media blitz will do to a person. Her kids, her accent, her state, her former brother in law, her husband, he clothes, nothing was off limits to the attacks.
You are right, this did not happen in 2 years but Fannie and Freddie's problems were brought up by Bush and the republicans in 2003 and again in 2005 and it was blocked by democrats. Perhaps you didn't see the video of the congressional hearings where the democrats praised the Fannie and Freddie executives and denied there were any problems and did not need regulation. Did you see the Maxine Waters video in the House Finance Committee heaping praise on Fannie Mae executives, or the fact Barney Frank's boyfriend was a Fannie Mae executive while Frank was fighting back regulatory reforms?
There is plenty of blame to go around for this boondoggle BUT you must be willing to call a spade a spade and admit the democrats in their obstructionist vitriolic way have a HUGE portion of the blame if you are to have ANY credibility.
