We noted last week that state Rep. Nikki Haley (R), an ally of Gov. Mark Sanford (R) and a candidate to replace him in the 2010 election, used the debate over whether he should resign to attack a potential rival, Lt. Gov. Andre Bauer (R). Now, in a sign of just how quickly Sanford's situation is deteriorating, she suggests that his additional revelations may require him to step down for good.

"There are no words to describe the disappointment I feel over the revelations of the past week," Haley says in a statement this afternoon. "The people of South Carolina have heard enough about the governor's personal life. We do not need to hear any more of that. What we do need to hear from the governor is an explanation as to how he can lead our state going forward. He has a responsibility to outline what he wants to accomplish over the next 18 months and how he intends to accomplish it. I remain willing to listen to that case, but if he cannot make it convincingly, then he must move on."
