Hillary Clinton's camp are trying to construct a Pyrrhic victory before our eyes.
Because Florida and Michigan moved up their primaries, the Democratic National Committee stripped those states of their delegates. Both Clinton and Obama accepted that decision; Obama wasn't even listed on the Michigan ballot. As a result, the campaign strategies of the two candidates were altered.
Now that Clinton is in a fight for her political future, she wants to go back on her word and have the results of those primaries counted, since she "won" them. She's trying to play it as an unfair disenfranchisement of the voters, but the tactic is transparently grasping.
If Clinton wins the nomination because of this, she will have destroyed the Democratic party. Already, her husband's legacy as President has been greatly diminished by his intemperate behavior on the campaign trail. She now risks political fratricide by forcing this Florida/Michigan issue on her supporters and colleagues. It is selfish and unstatesmanlike.
She can yet head off disaster by immediately reiterating her support for the DNC sanctions, but I don't see it happening. This is her moment in history, and she sees it slipping away from her, like anxious Orpheus.
