David Broder in the Washington (Republican Propaganda) Post:

The saga of South Carolina Gov. Mark Sanford and his Argentine romance has been such ripe fodder for the gossip mills that the essential governmental question has almost been forgotten.

Whether Sanford can resolve the mess he has made of his personal life is of little concern to anyone but the people involved.

But when he disappeared for five days, telling no one in his administration or even his security detail where he had gone, he did something totally irresponsible. Had any kind of emergency occurred, South Carolina would have been leaderless.

At the moment Sanford abandoned his duties in secret pursuit of private pleasure, he in effect tendered his resignation.

The Legislature should insist he follow through on it.
