Few Americans could have been as deeply disappointed as me to hear John Edwards’ recent admission of an affair two years ago — confirming tabloid rumors that, like many, I had refused to believe. An early and ardent supporter of his candidacy, I had considered him above such indiscretions. Yet, I cannot get past the outright disgust over the needless waste of time and attention now devoted to what is in truth a moot issue, with probably the most critical election in decades quickly bearing down on us.
