but at the same time, it's a sound strategic move. The more inevitable he seems, the more money flows to him and less to Clinton. The more superdelegates endorse him and leave Clinton.
It's not moving the goalposts...it's declaring victory before the final whistle with a nearly insurmountable lead.
Probably best to wait, but politically, it's a smart move! If Hillary wants to insist that she still has a chance, despite the obvious, then Obama certainly has the right to insist that he's won!
