According to South Carolina's Governor for the moment, Mark Sanford, God wants him to finish out his term as governor. Somehow, I doubt that he got that message from a burning bush.
I find Gov. Sanford's invocation of God as supporting his decision to be substantially the same as Iran's mid-level cleric-cum-Supreme Guide Khameini invoking God as having supported the landslide reelection of Ahmedinejad. Both are making despicable use of religion to support the unsupportable. They claim divine intervention to color their obvious moral wrongs. Both are equally detestable and do harm to their respective religions by their actions.
The only difference between the two is that Khameini should be hung for the murder and repression he has ordered in the wake of his illegal acts. Sanford should be prosecuted for misuse of state funds. Beyond that, both will ultimately answer to a higher power whom I doubt will take a permissive view of their actions.
