So we now know where Mark Sanford, Republican governor of South Carolina and would-be presidential contender, has been, and it sure wasn’t hiking:

After going AWOL for seven days, Gov. Mark Sanford admitted Wednesday that he had secretly flown to Argentina to visit a woman with whom he was having an affair. Wiping away tears, he apologized to his family and gave up a national Republican Party post, but was silent on whether he would resign.

“I’ve been unfaithful to my wife,” he said in a news conference in which the 49-year-old governor ruminated on God’s law, moral absolutes and following one’s heart. He said he spent the last five days “crying in Argentina.”

He betrayed his family and blew off his state for a week, apparently out of self-pity.  Get him out.
