Clinton and Lewinsky's relationship was a case of two adults having a consensual relationship. Extramarital, yes, but consensual, and not a crime. It wasn't Lewinsky that made the affair public. It was Linda Tripp. The reason why I don't criticize Clinton for it is because it's none of my business, nor is it anyone's business other than Monica, Bill and Hillary's.
"nor is he taking Hillary to task"
Why should I?
