Are you guys blind? Under PELOSI the DA PASSED in the house! It was only turned down in the senate which she has no control over. Pelosi by bar is the biggest contributor for it passing in the house. She has the ability to rally votes, and many Repugnants dislike her because of how she ran the house and get things done!
What happened when they lost the majority? NADA. The whole political system pretty much collapsed and contributed to the whole economic turmoil.
Obama is right giving her credit. It was Obama not doing enough in the senate to help Reid/Durbin.
