Isn't it sad that Killefer and Dashcle had to be the ones that withdrew their names?

Why is it that Nancy Killefer and Tom Daschle can clearly see that they are not the people to hold positions of trust in the Obama administration, but Obama himself cannot see it? If he could, he would have never allowed Timothy Geithner to become Treasury Secretary after his tax debacle. What happened to Obama's promises of change? Were all those campaign promises lies? Does he not understand that the American public is outraged at the corruption in Washington?
