What was Gov. Mark Sanford Thinking When Attacking Clinton's Values?

The question sounds sarcastic, but I'm not sure it is. I think there might be a gap in the perceptions of people who see themselves as fundamentally honest but fallible, while seeing their political opponents as foul. From the outside it looks like a pretty filthy streak of hypocrisy, but I'm not sure that all the politicians are conscious of it. Do you think he was being openly hypocritical when attacking Clinton? If we could figure out what was going through Sanford's head, is this one of the hints towards conservative in-group thinking?
