Let's consider the chain of events: Clark mentions to reporters that Kerry will fall due to an "intern" scandal; Clark drops out of the race; Clark immediately endorses Kerry; Pundits exchange quizzical glances.
Gee whiz, why would Clark endorse Kerry immediately after outing him?
Maybe, just maybe, the reason Clark endorsed Kerry so quickly was as an act of contrition. Maybe he realized he hadn't quite gotten his facts straight when he made the accusation.
If only Drudge would do the same.
