Love Gov. Mark Sanford has a much better adultery defense than debating the meaning of "is"; technically, he never promised wife Jenny that he'd be faithful, in fact, he cut fidelity out of their wedding vows. Jenny recently told 20/20's Barbara Walters that although "it bothered me to some extent" that Mark wanted the faithfulness clause excised, she "got past it...along with other doubts that I had," made a "leap of faith," and married him. Jenny added, "I thought he loved me in his own way, which is not a warm, bubbly way." And given his Argentine paramour, apparently not a "you're my soul mate" way either.
