I suppose I agree with the CW that it was a mistake for Obama to be baited into responding to Hillary, but I’m not sure how much a pointed press statement is going to hurt his positive image in the long run and the usual rule of thumb in such things is that it is a mistake for a front-runner ever to “attack down” against a trailing candidate. The big beneficiary here is probably John Edwards, who might be able to come up the middle if there’s a bruising Hillary-Obama fight, just as he came up the middle in Iowa in 2004 when Dean and Gephardt pounded one another. Also, the sheer Nixonian slipperiness with which Edwards is managing to attack Hillary in the harshest terms while at the same time denying he is attacking her is something to behold.
