Though some cads can be somewhat lovable or redeemable, "John Edwards is not," columnist Eugene Robinson wrote. "His caddishness, it appears, has no redeeming social or political value. He's just a bad cad." Robinson noted claims by a former close aide that not only is Edwards the father of his mistress' 19-month-old daughter, Edwards allegedly promised the mistress that he would marry her after his wife, Elizabeth, had died of cancer, and that they had started to plan the wedding. "The forgivable kind of cad could never do such a thing," Robinson wrote. "Only the worst kind would."
