I agree with you, but Obama obviously does not else he would not have made the claims he made. Either that or Obama knew and was just lying to everything with the understand that most people are idiots who believe his lies.
Either way, not a good thing. I take Obama to task for the things Obama claimed. Had he not made the claims there would be nothing to take him to task for. Squarely his fault...Obama cannot blame Bush for the things Obama has said.
There is another possible answer. He, well actually his advisors, could have just been plain wrong at the time. People are wrong sometimes, I tend to look at how they react and adjust strategy/thinking after they figure out they are wrong more than the original mistake.
Hell, even if he flat out lied he is a damn politician. Thats not very newsworthy, as sad as that is.
