Is Adultery a Crime?

Leaving aside the moral implications of my question, what I am really asking here is does the act of adultery violate a criminal law. At the turn of the century . . . the 19th century . . . all states had laws punishing adultery. The punishment ranged from flogging to imprisonment. But today no one talks, for instance, of charging Tiger Woods with a crime. But could we? Apparently, the answer is yes, at least in some states. The Associated Press has more.
