No, I do see Pelosi as being the real power behind the push. Gradually, Obama started to very slightly distance himself enough to say "I want healthcare because it's what I promised" but that was probably in large part due to Pelosi having to turn her attention to her own campaigning. Obama never seemed very comfortable with the way things were going early on, and always seemed like he at best only half way believed what he was advertising. Meanwhile, Pelosi was slipping free condoms into the stimulus package because it "cut costs" over paying the welfare benefits for new children. Say what you want about Obama, but you can't possibly paint him as being stupid enough to come up with, or back, shit like that on his own accord.
