Maureen Dowd, writing on the dual personalities of Mark Sanfordand Marco, his hedonistic alter-ego who ran off to an Argentinian amorata while pretending to be hiking the Appalachian Trail or writing or something :

"... Jenny Sanford told The Associated Press on Friday that Mark had told her he needed time to be alone and write, so she was stunned to learn he was in Argentina on a "Roman Holiday." Before he left to "write," she warned him not to skip off to the other woman.

Mark, who disdains rascals, agreed that he wouldn't. Marco, who is a rascal, skipped off.

Mark went back to work on Friday, giving his cabinet a lecture on personal responsibility and comparing himself to King David, who "fell mightily ... in very, very significant ways but then picked up the pieces and built from there."

Actually, the one thing David didn't do after his adulterous fall was build, because he was forbidden by God to construct his dream temple in Jerusalem.

Sanford should give his piety a rest. He told his cabinet that the Psalms taught him humility. (There's a chance that a younger Argentine boyfriend of Maria's also taught him humility, by jealously hacking into her e-mail account and leaking the governor's missives.)

Sanford can be truly humble only if he stops dictating to others, who also have desires and weaknesses, how to behave in their private lives.

The Republican Party will never revive itself until its sanctimonious pantheon — Sanford, Gingrich, Limbaugh, Palin, Ensign, Vitter and hypocrites yet to be exposed — stop being two-faced. "
