Democratic Candidates Debate: Must They Tread Lightly on Clinton in Hostage Crisis Aftermath?

Press corps sees Clinton as "presidential" in handling potential tragedy.   AP: "The picture of calm in the face of crisis."   Politico: " The scene was one of a woman in charge."   Two potentially huge anti-Clinton moments -- well-received Edwards/Obama DNC speeches and Bloomberg-Obama mystery meeting -- completely obliterated by crisis.   Update: Decent interval passes by midday Saturday, as rival campaigns begin to send around negative information about Clinton.
