Cole links to a comment on his site:

Looking over the race, how much of Obama’s criticism of Clinton have been of the nature that would harm her and the party’s chances in the general election? I seriously cannot think of any. While everything — EVERYTHING — coming out from the Clinton camp is stuff that can be picked up and used by the Republicans in one way or another or is designed to damage him as a candidate going forward as much if not more than it impacts him now…

He seems to have stuck more or less to contrasting the two of them before Democrats while she goes on stage last night and claims he’s not ready to be President.

Absolutely. The context for that post, by the way, is that the Clinton camp is creating a new 527 to attack Obama. Joy.
